A
Overview
The Cedex Analyzer automatically determines the cell concentration and viability of cell suspensions. The
analysis is based on the Trypan Blue Exclusion Method whereby cell suspensions are stained and analyzed. The
data obtained allows for the evaluation of the overall state of the cell culture, including the specific growth rate
and doubling time of a cell population, as well as the documentation of the cultivation process.
A
The evaluation of the samples is based on automatically obtained digital images that are analyzed using analysis
software on a separate computer (Cedex Control Unit). All the necessary steps – from the staining of the samples
to the recording and evaluation of the image data – are automatically performed by the analyzer. Recognition
and differentiation of cells as either viable or dead is done under standardized conditions, which provides very
precise and objective results.
A variety of parameters, including Viable Concentration, Total Concentration, Viability, Total Object Count,
Average Compactness and Average Diameter are analyzed using result data from single images, as well as from all
of the selected images of a sample. Standard deviation (Std. Dev.) of the number of cells from image to image
is also calculated. In addition, the Aggregate Rate, which shows the percentage of the total number of cells that
appear in aggregates (clusters), is determined for both single images and all of the images. The use of a Live
Operator makes it possible to directly observe the effects on the analysis of a sample when the image analysis
software (Operator) is adjusted.
Graphical representations of the measurement results can be viewed in the Measurement Statistics Histogram,
Diameter Histogram, Compactness Histogram, Aggregate Histogram and Cultivation Time Chart. In
the Measurement Statistics histogram, individual images can be compared to give a better overview of the
distribution of the cells in the images. The Cell Diameter Histogram shows the diameter distribution of living
cells. The deviation of the shape of living cells from that of an ideal sphere is represented in the Compactness
Histogram. The Aggregate Histogram provides an overview of the amount and size of aggregation found in the
cell culture.
The Cultivation Time Chart displays growth curves and cultivation parameters in a time- dependent manner.
The results of the Cultivation Time Chart can be separately printed out. For further processing of the results in
other programs, data export in formats such as Excel-compatible formats and CSV (Comma Separated Values,
generally applicable) is possible. The Cultivation Time Chart includes calculations for the doubling time [T]
and specific growth-rate [µ].
The Cedex Software 2.2 can be operated on Windows® XP Professional. Secure data handling, as well as a
carefully designed user management system, guarantee compatibility with 21 CFR, Part 11. Access security for
the Cedex Analyzer has been stepped up. Access is only allowed for authorized persons. The workstation can be
automatically blocked after a certain number of consecutive entries of a false password via the Systems Options.
A warning message will appear before the last allowed attempt.

Description of the Cedex System

1
Description of the Cedex System
The Cedex System consists of two functional units, the Analyzer (see Figure 1) and the Control Unit (computer
equipped with the Cedex Software 2.2).
Preparation and processing of the samples takes place in the analyzer. The analysis software is installed on a
computer and controls the analyzer, as well as the analysis and evaluation of the images obtained.

Figure 1: The Cedex Analyzer
The Analyzer consists of two main components, the hardware for image capturing and the Liquid Management
system.
The flow chamber is specially developed to allow for the analysis of a defined volume of cell suspension. The
Liquid Management system is responsible for staining the sample as well as for filling and cleaning the flow
chamber and liquid feed system.
The volumes of sample and dye, as well as specific cleaning solutions required for each cleaning routine, are
precisely controlled via the syringe module with the 8-way distribution valve. The individual components of the
Liquid Management system are easily accessible to allow for trouble-free maintenance and control.

The Measurement Procedure
The Trypan Blue Exclusion Method
2
The Measurement Procedure
The determination of the number of viable cells (cells/ml) and viability of cell suspensions (the percentage
of viable cells from the total cell sample) is a fully automated, standardized procedure based on the manual
Trypan Blue Exclusion Method. A defined volume of Trypan Blue is added by the syringe to the Cedex Sample
Cup containing the cell suspension. The cell suspension and dye are optimally mixed between the syringe and
Cedex Sample Cup by controlled pump actions and then incubated for exactly same amount of time for each
measurement. This minimizes effects on the viability measurements that might be caused by the toxicity of the
Trypan Blue.
A
After the incubation period, the stained cell suspension in the syringe is then transported in small portions
through the capillary tubes and 8-way valve to the flow chamber. A set number of microscopic images of the
cell sample is taken in the flow chamber and transferred to the analysis software via an integrated interface in
the measurement system.
Once the measurement procedure is completed, a cleaning routine is automatically performed by the Liquid
Management system. It is only possible to begin a new measurement after the cleaning routine has finished.
2.1
The Trypan Blue Exclusion Method
The Trypan Blue Exclusion Method is based on the principle that viable cells will not take up the dye, while dead
or dying cells have a compromised membrane that allows for the uptake of the dye. Thus, dead cells will appear
darkly stained in a microscope.
Trypan Blue has a greater affinity for serum proteins than cellular proteins. If the microscopic image has a
dark background due to high quantities of stained serum proteins, centrifuge the cell sample and re-suspended it in a protein free-medium or physiological saline solution prior to counting.
Overview
21
Data Analysis
A
3
Data Analysis
The analysis software and its graphical user interface (GUI), known as the Cedex Control Center, enables the
user to work with the Cedex Analyzer. The image analysis software (Operator) recognizes structures and identifies particles, thus differentiating cells from cell debris and dirt particles. Live and dead cells are differentiated
according to their degree of Trypan Blue staining.
Image processing is integrated in the Cedex Control Center in such a way that the user or Administrator can
check on its function in the system. The analysis process cannot be altered during data recording in order to
allow for consistent and objective measurement results.

Completing the Windows Mini-setup
3.1
Completing the Windows Mini-setup
When starting the Cedex Control Unit for the very first time, a Windows mini-setup may run. The setup allows
the user to tweak the final settings of the new system (e.g. selection of time zone, keyboard etc.). The mini-setup
dialogs should be self-explanatory. The following list provides some additional information to get through the
process. Note that the order of screens may be different and some topics may not appear on your system:
B
Roche technical services strongly recommends not changing the regional settings. Changes in the regional
settings may result in problems with date and time format within the Cedex Software.
You may be required to enter the 25-digit product code. It is located on the Control Unit.
Protect your PC: Roche technical services recommends turning on automatic updates if the Control Unit is
permanently connected to the internet via a LAN. Otherwise, click no, not right now.
Computer name: The Control Unit name has already been set to a unique name. However, your company
might enforce a different naming convention. If you are not sure, leave it as it is. The name can be changed
at any time later on.
Computer description: This is a purely informational field that helps to identify the Control Unit in a
network. You may want to enter a short descriptive text. Again, this setting can be adjusted later.
If asked to choose an Administrator account password, be sure to make a note of the password and store it
in a safe place.
If asked to choose whether to add the computer to a domain, Roche technical services recommends
choosing No. Your local network policy may require a different strategy, but you are free to join a domain
any time later on.
Register with Microsoft: It is not necessary to register your Windows copy with Microsoft, so No can be
safely chosen. Note that registration is not activation (see below).
Internet account setup: The operating system has been configured for access to the Internet over a Local
Area Network (LAN). Roche technical services recommends clicking No and proceeding to the next step.
When the mini-setup has finished, the Control Unit will automatically restart and present the login screen
after a short while.
Some Control Units may require immediate Windows activation. Follow the instructions on the screen.
Roche technical services recommends activation over the internet if the Control Unit is already connected

Updating Older Cedex Software version 2.x to Cedex Software 2.2
4.3
4.3.1.
Overview
Before starting an update of your current Cedex Software 2 installation to Cedex Software version 2.2, ensure
that:
You have Administrator access to the Control Unit.
The Firebird database password (i.e. of the SYSDBA account) is available in case it has been changed, e.g.
because the installation has been made 21 CFR Part 11 compliant.
A storage device with enough disk space is available for a backup of the current installation. Check the
size of the folder containing all Cedex Software 2 files, including the database file (usually the directory
C:\Cedex2). The size of the backup will be approximately the size of this folder.
Enough time is scheduled for a backup of the current installation (approximately one hour for backup to a
fast external hard drive per 10 GB disk space used in the Cedex2 directory, including the database file).
4.3.2.
B
Updating to Cedex Software 2.2
Make sure that you have created a backup of the Cedex Database and that you have fully read and understood
the following instructions before proceeding with the update of the Cedex Software! If an error occurs or if
you do something wrong, this could result in data loss and/or could prevent the Cedex Software 2.2 from
operating!
1
Run the Cedex 2.2.1.exe from the install CD by double-clicking on it.

By default, Cedex Software version 2 is installed under the directory C:\Cedex2.
If your software was installed under another directory, the field under the Cedex 2 directory line must be
changed to the appropriate directory. Change the entry in this field by clicking on the change button next to
Cedex 2 directory field.
5
By default, the location of the Cedex Software database file is C:\Cedex2\DB\CEDEX.FDB. If the database file is
in a different location, the field under to the Cedex 2 directory must be changed to the appropriate pathway.
Change the Cedex 2 database file if it is not C:\Cedex2\DB\CEDEX.FDB by clicking on the change button
next to Cedex 2 database file.
6
If the password of the Firebird database administrator SYSDBA has been changed (e.g. because the system
has been made 21 CFR Part 11 compliant), uncheck use standard SYSDBA password (“masterkey”). In
this case, the database password will be requested just before the update is carried out.
To create the backups successfully, it is necessary that the user account used for updating has read access
to the Cedex2 directory and Cedex Database file. Verify the backup files before proceeding with the
update!

4.3.3.
Restoring a Cedex Software 2 Backup
This procedure should only be carried out in case a failure occurs during installation of the Cedex Software
2.2 update as described in “Updating to Cedex Software 2.2”. Carry out this procedure only after consultation
with Roche technical services!
If you choose to restore the backup, all data stored in the current database will be overwritten by the data
stored in the backup database! This means, for example, all measurements and all configuration changes
carried out on the system after the original backup was made will be lost, even if the measurements have been
archived or exported.
Carry out the following steps to restore the Cedex Software 2 backup that was created in step 7 in the chapter
“Updating to Cedex Software 2.2”:
1
Locate the active Cedex2 folder on the hard disk. It is usually located at C:\Cedex2, which is the default
location selected during installation. Delete the Cedex2 folder by right clicking on it and selecting Delete:
B

Securing Access Rights
6.1
Access Control at the Windows Operating System Level
We recommend choosing your local IT specialist as the system administrator for the general administration of
the Windows operations. This person should undertake the configuration of the settings that regulate access to
the system at the operating system level. One default user at the operating system level has been factory installed:
The Win-Admin user (default password Win-Admin) acts as system administrator for the operating system
and has full access to all elements on the desktop including the ability to add/delete programs.
6.2
Access Control at the Cedex System Software Level
To launch the software, do the following:
1
Check that the Cedex Server software has already been automatically started (it may appear as a minimized
window in the task bar at the bottom of the computer screen). If it has not automatically started, start the
server by double-clicking on the Cedex Server icon on the desktop.
2
Start the Cedex Software 2.2 by double clicking the Cedex Client icon on the desktop (the Cedex Server
must be successfully launched before the Cedex Client can be started). The Log In window of the Cedex
System will open.
3
Enter the username password in the respective fields. By default, the following users are available after
installation:
a. Superuser (password spass)
b. Administrator (password apass)
■
For the Cedex Software, there should generally be at least three levels of users. In addition to normal Cedex System
users, who will only use the Cedex System for carrying out measurements, both a Cedex System Superuser
and an Administrator should be appointed. The Cedex System Superuser assumes the main responsibility of
handling the Cedex System, whereas the Administrator creates and administers user accounts.
For security reasons, both the Administrator and the Superuser should protect their access to the Cedex Software
2.2 with new passwords after initial installation. Follow the instructions below to secure access and define a new
password:
1
Log in as Administrator or Superuser.
2
Click on the System menu in the Cedex Control Center.
3
Click on Change own password. The Change Password window will appear.
4
Enter the old password first. The new password needs to be entered twice.
5
Confirm by pressing OK.
■
After logging in, users can change their own passwords at any time by following the same procedure.
After installation, the user Administrator should set up regular user accounts and provide the necessary rights
before regular users run measurements (see “Administration of User Accounts”).
For security reasons, the Cedex System Administrator is generally only accorded administrative rights and
cannot carry out, reprocess or view measurements.

Operation
47
Performing a HW Startup and Prime
2.4
Performing a HW Startup and Prime
Two elements of the analyzer are usually shut down at the end of the day: the Hardware Management and the
Liquid Management. When the Hardware Management is shut down, several elements of the analyzer, such
as the Multi Sampler and pump, are not yet initialized. A HW Startup will initialize hardware interfaces and
must be done before a measurement can be performed. If a measurement is attempted before the Hardware
Management has been started, an error message will appear, “Cannot start a new process: Hardware
Management is not started”. The HW Startup may be automatically carried out when the software is launched
if the Administrator has set this up in the system options.
C
In the case of the Liquid Management, the capillary tubes and syringe are filled with air or water when the
analyzer is first installed or any time an LM Shutdown has been performed (see, “Carrying out an LM Shutdown
and HW Shutdown”). Performing a Prime will fill the capillary tubes and 8-way valve with the appropriate
reagents. All measurements are based on the capillary tubes having a precise amount of reagents in them.
Not performing a Prime will lead to cell samples being incorrectly stained and, consequently, inaccurate
measurement results.
A Prime must, therefore, be performed after an LM Shutdown has been executed in order to run a measurement.
Since LM Shutdown should be run at the end of the previous day, a Prime is necessary prior to the first
measurement of the day. No measurement is possible without performing a Prime first. If a measurement is
attempted before the machine has been primed, an error message will appear, “Cannot start new process: system
is not primed”.
Both the HW Startup and the Prime functions are located in the same window. Follow the instructions below
to perform a HW Startup and Prime:
1
Click on the HWM button in the Cedex Control Center or else select Hardware Management under the
Functions menu. The Hardware Management window will open.
2
If the Hardware Management has not been started, the current status field will have the message “HW not
started and LM not primed”.
3
Click on HW Startup if required. The Hardware Management will start and the current status field will have
the message “HW started and LM not primed”.
4
Ensure that a Reagent Kit is installed (see “Preparing the Reagent Kit”) and a clean, empty Cedex Sample Cup
is correctly attached to the sample port or correctly positioned on the Multi Sample Tray, if present
(see “The Multi Sampler DefaultCup”).
5
Click on Prime. The duration of a Prime procedure is displayed in the Estimated total time area. The time
displayed is an estimate based on the time required for the previous Prime. The message “HW started and
LM primed”, appears in the current status field when the Prime has been completed.
6
Click on
to close the window.
■
There should not be a break of more than 2 hours between a Prime and a measurement. If more than 2 hours
have passed since the last measurement, a new Prime must be performed.
48
Preparing the Reagent Kit
2.5
To ensure optimal performance, the reagents must be free of impurities such as dust, crystals, biological material
or fluff. The Roche Diagnostics GmbH Cedex Reagent Kit guarantees optimal handling with the best possible
safety. One Reagent Kit pack is sufficient for approximately 100 measurements, including the standard cleaning
routines.
2.5.1.
Installing or Changing the Reagent Kit
Proceed as follows to install or change the Reagent Kit:
1
Perform an LM Shutdown if the Liquid Management system has been primed (see “Carrying out an LM
Shutdown and HW Shutdown”).
2
Open the new Reagent Kit and place the Reagent Kit containers in the appropriate positions on the reagent
tray (see Figure 38).
3
Fill the water reagent container with distilled or de-ionized water.
4
Empty, clean and replace the waste container.
5
Connect the capillaries to the reagent bottles through the holes in the lids. Ensure that the capillary tubes
are not bent and almost reach the bottom of the containers. Use the lids to close the reagent containers to
avoid dirt-particles getting into contact with the reagents.
C
The tubes should not be shortened under any circumstances!
6
Remove the lid of the waste container and ensure that the silicone and capillary tubes only reach about 1 cm
into the container.
7
Select the Reagent Kit Status option in the Functions menu of the Cedex Control Center. The Reagent
Kit Status window will open.
8
Click on the Replace all containers button in right-hand corner of the Reagent Kit Status window to
confirm the changing of the Reagent Kit (see Figure 39). The Reagent Control display at the bottom righthand corner of the Cedex Control Center will turn from red to green and indicate the number of runs left.
9
Attach a clean Cedex Sample Cup to the sample port (see Figure 40) or place it in the DefaultCup position
on the Multi Sample tray (see “The Multi Sampler DefaultCup”).
10
Click on Prime in the Hardware Management window.

Figure 38: Position of the Reagent Tray with the individual containers
Figure 39: Confirming change of the Reagent Kit
For reliable functioning of the reagent control (correct number of possible measurements, or reporting an
impending overflow of the waste container), it is critical that all of the reagent containers are correctly
filled to the line with the appropriate liquid or, in the case of the waste container, completely emptied (see
“Refilling Containers Individually”). The changing of the reagents must then be confirmed appropriately in
the software as soon as the Reagent Tray has been put back into the chamber. Failure to do all of the above
will result in a mismatch between the calculated reagents available as shown in the Reagent Control and the
actual reagent amounts in the containers or space available in the waste container.
The reagent control function that monitors reagent and waste levels can be turned off. See “Disabling the
Reagent Control”, for more information.
50
2.5.2.
Refilling Containers Individually
In order to ensure optimal functioning of the analyzer, each Reagent Kit container must be thoroughly cleaned
before refilling. Impurities such as dust and fluff or contamination with micro-organisms may thus be avoided.
Reagents can be refilled, or emptied in the case of waste, on an individual basis. Each change can be individually
confirmed by clicking on the respective Set Full button or Empty button, in the case of waste, in the Reagent
Kit Status window (see Figure 39).
If you are using your own reagents, it may be necessary to filter them before use. Roche Diagnostics GmbH
recommends using the Cedex Reagent Kit.
To refill individual containers with reagents, follow the instructions below:
1
Rinse all reagent containers well before refilling! Ensure there are no impurities such as dust or fluff in the
containers.
2
Fill the detergent container to the required level with Cedex Detergent (see label or bottom of container).
Only Cedex Detergent or a detergent with identical specifications should be used for the cleaning procedures
in order to prevent damage to the sensitive surface of the Liquid Management components.
3
Fill Roche Diagnostics GmbH Cleaning Solution in the cleaning solution container to the required level
(see label or bottom of container).
4
Fill distilled or de-ionized water in the water container to the required level (see label or bottom of container).
5
Fill 0.2% Trypan Blue solution in the Trypan Blue container to the required level (see label or bottom of
container). Roche Diagnostics GmbH recommends using 0.2% Trypan Blue solution. If necessary, dilute a
more concentrated Trypan Blue solution with buffer (Phosphate Buffered Saline (PBS), pH 7.4).
6
Place all of the reagent containers, as well as the emptied waste container, in the appropriate positions in the
Reagent Tray (see Figure 38).
7
A Cedex Sample Cup should always be attached to the single sample port (see Figure 40). The Cedex
Sample Cup (4 ml) is correctly attached when it is in an upright position beneath the sample port and the
capillary tube almost reaches the bottom of the Cedex Sample Cup. If there is a Multi Sampler connected to
the analyzer, a Cedex Sample Cup must be placed in the DefaultCup position on the Multi Sample Tray
(see “The Multi Sampler”).

Checking the Analyzer
2.6
Checking the Analyzer
Since measurement results obtained with the Cedex Analyzer depend on correctly filled reagent containers and
the proper performance of the analyzer, the user should check the analyzer for possible wear and tear, and also
check whether the reagent containers have the correct volume prior to each set of measurements, as follows:
C
52
1
Check the syringe module (2.5 ml syringe and 8-way valve) for wear and tear or contamination. Renew the
syringe if required (see “Syringe Maintenance”).
2
Check the number of runs possible. This is listed in the right-hand corner of the Control Center next to
a green or red circle. Change the Reagent Kit punctually. Observe the reminder to change the Reagent Kit
(see “Installing or Changing the Reagent Kit“).
3
Check whether there is an empty Cedex Sample Cup attached to the sample port or a Cedex Sample Cup
in the DefaultCup position on the sample tray in the case of a Multi Sampler. If there isn’t, attach one
(see Figure 40 or “Working with the Multi Sampler“).
4
Perform a Hardware Management (HW) Startup if necessary.
5
Perform a Prime if a Reagent Kit is installed and new measurements are to be carried out (see “Performing a
HW Startup and Prime”).
6
Have the cell suspension samples or particle solutions ready for the analysis.
■
Carrying out a Single Measurement
3
The following section describes the procedure for carrying out a single measurement. For setting up and
carrying out multiple measurements, see “Working with the Multi Sampler”.
A number of relevant parameters and entries must be specified in the Measurement window prior to carrying
out measurements. They include:
Choosing the operating mode and specifying sample data.
Defining the measurement and analysis (process) parameters.
The measurement procedure can only begin when the steps above have been completed.
Perform a HW Startup and Prime prior to the first measurement if the Liquid and Hardware Management
system were previously shut down (see “Performing a HW Startup and Prime”).
Operation

53
Opening the Measurement window and specifying the Operating Mode and Sample Data
3.1
Opening the Measurement window and specifying the Operating Mode
and Sample Data
Open the Measurement window either by clicking on the Measure button in the Shortcuts area or by selecting
Single Measurement in the Measurements menu. The entry areas for choosing the desired operation and
specifying the sample data are located in the Sample Parameters and Processing parameters areas of the
Measurement window. The parameters should be entered just before measuring in order to ensure a direct
relationship between the sample and the data.
Follow the instructions below to specify sample data for a single measurement:
C
1
Open the Measurement window by clicking on the Measure button in the Shortcuts area or by selecting
Single Measurement in the Measurements menu.
2
Enter a clearly defined Reactor ID to describe the sample (e.g., the name of the cell culture) in the Reactor
ID area. You may either choose a Reactor ID from the drop down list or enter a new Reactor ID. A new entry
can be defined by up to 20 alphanumerical symbols.
3
Enter a clearly defined Sample ID in the Sample ID area (e.g., P001). The Sample ID can be freely defined.
If the intended measurement is not the first in a row of measurements, i.e., if it has the same Reactor ID
as a previous measurement, then the software will automatically enter the consecutive Sample ID into the
Sample ID area (e.g., P001, P002,...). In that case, it is not necessary to enter the Sample ID manually unless
a different Sample ID is desired.
4
If desired, use the Sample Drawing drop-down menu to select the date when the sample was drawn. Note
that the process date and time, i.e., the date and time the sample was measured, is automatically entered.
5
Choose the appropriate dilution factor from the Dilution drop-down list (e.g., 1:1, 1:2, 1:5… etc.).
When a dilution of 1:2 is prepared, then 1 part cell suspension has been added to 1 part dilution medium.
A dilution of 1:5 means that 1 part cell suspension has been added to 4 parts dilution medium. For undiluted
samples, a dilution factor of 1:1 should be entered. It may be necessary to dilute samples with very high
cell densities ( >1 × 10 7 cells/ml) manually prior to measuring. The dilution ratio chosen from the drop
down list only relates to the manual dilution of the sample prior to placing the sample on the system.
Dilutions that are an automatic part of the measurement process in the analyzer are already taken into
account by the Cedex Analyzer software. The calculations are carried out automatically and have nothing
to do with the entered dilutions.
6
Select the sample volume of 1000 µl in the Volume drop-down menu. Currently, only the 1000 µl option is
available for the Cedex Analyzer.
7
The System name, as well as the process date and time of the assignment, will be automatically transferred
to the “Processing parameters” area in the Measurement window.

Defining the Measurement and Analysis (Process) Parameters
3.2
Defining the Measurement and Analysis (Process) Parameters
The measurement and analysis parameters are defined in the Processing Parameters area of the Measurement
window. In principle, all routine measurements can be carried out using the standardized default settings that
are factory set. To change the settings, follow the instructions below:
1
Select the sample port type in the Sample Port drop-down list:
Auto: this option will only appear on systems with Multi Samplers.
Single: this option will only appear on systems with a single sample port.
2
Manually enter the cup position for the sample in the Cup Position window if there is a Multi Sampler
(see “Working with the Multi Sampler”).
In the case of single measurements run via the Measurement window on a Cedex Analyzer with
a Multi Sampler attached, the software will automatically incrementally increase the sample cup
position number with each new measurement. The cup position can also be fixed
(see “Turning off automatic incrementation of sample cup position”).
3
Select the Cell Type that optimally recognizes your cells from the Cell Type drop-down list
(see “Adjustment of the Image Analysis using the Live Operator”).
The following Cell Type is available by default:
Std. Cells (V5.00) for normal sized cells with a diameter of about 12 µm, e.g., HB58
If a new Cell Type has been created, it can also be selected from the same Cell Type drop-down list.
See “Adjustment of the Image Analysis using the Live Operator” for more detailed information about creating
new Cell Types.
4
C
Select the desired precision level in the Precision drop-down list. The precision level determines the volume
to be analyzed. A higher analyzed volume will require a somewhat longer measurement time but more cells
will be counted, which will lead to a more precise calculation.
Minimum: approximately 10 images are used for the analysis.
Normal: approximately 20 images are used for the analysis.
Superior: approximately 30 images are used for the analysis.
The precision names may appear differently if the system has been upgraded from some previous version
to software version 2.2. In the case of a system that has been upgraded to version 2.2, the precision levels
may be called Low (corresponding to Minimum), Medium (corresponding to Normal) and High
(corresponding to Superior). The same volumes are analyzed for the corresponding levels.
5
Prepare the sample and attach the Cedex Sample Cup containing the sample to the sample port or place
it in the appropriate spot on the Multi Sample Tray (see “Preparing the Sample and Attaching it to the Multi
Sample Tray or Sample Port”, below).

Preparing the Sample and Attaching it to the Multi Sample Tray or Sample Port
3.3
Preparing the Sample and Attaching it to the Multi Sample Tray or
Sample Port
Prepare the sample prior to measuring according to the following instructions:
1
Transfer the selected volume of a well-mixed cell suspension to a clean Cedex Sample Cup.
The Cedex Analyzer tolerates volume variations of +/- 10%. Any greater variation in sample volume will
lead to inaccurate results, and the Reagent Control monitor will no longer function correctly. The Cedex
Analyzer can determine cell concentrations in the range of between 5 × 10 4 – 1× 10 7 cells /ml. Any
higher concentration requires a manual dilution. Cells with a diameter range of between 8 µm – 40 µm
can be assessed accurately.
2
Remove the present Cedex Sample Cup from the sample port (or Multi Sample Tray).
3
Attach the prepared Cedex Sample Cup containing the cell suspension to the sample port (see Figure 40;
the Cedex Sample Cup is correctly attached to the sample port when it is in an upright position directly
beneath it and the capillary tube almost reaches the base of the Cedex Sample Cup) or place in the
appropriate cup position on the Multi Sample Tray (see Figure 42).
C

3.3.1.
Starting the Measurement
First ensure that the entire measurement system, including the sample, is ready for a measurement as follows:
1
Ensure that the Cedex Sample Cup is correctly attached to the sample port or placed on the Multi Sample
tray.
2
Ensure that the reagent containers are sufficiently filled and in their correct positions.
3
Ensure that the waste container is empty.
4
Click on Start Measurement in the middle of the Measurement window to begin the measurement.
■
During the measurement, samples of the cell/trypan blue mixture are injected into the flow chamber in
successive steps. After each injection, an image of the sample is taken and sent to the computer for analysis. The
number of images taken depends on the precision level determined for the measurement.
56
Preparing the Sample and Attaching it to the Multi Sample Tray or Sample Port
3.3.2.
End of Measurement
A cleaning procedure automatically begins immediately after the last image is captured and the results have been
displayed in the Measurement window. The entire Liquid Management system is rinsed during this procedure
(Ultra Fast Clean). Once this procedure has been completed, a green bar appears in the Measurement window.
In addition, the message “Process finished EndEvent (Measurement)” appears in the Event window on the
Cedex Control Center.
In the Measurement window, the top section of the Result Data area displays the overall results of the
measurement. The bottom section displays, in succession, the results from each image taken. When a line is
selected in the list of results of single images, the corresponding image will be displayed in the Image area (see
“Image Area”).
C
Figure 41: Cedex Analyzer Measurement window with the final results
The measurement results can be directly printed out via the Print button in the middle of the measurement
window.
To set up a new measurement, click on the New Measurement button in the middle of the Measurement
window. If the next measurement belongs to the same Reactor ID as previous measurements, then the
consecutive Sample ID will automatically be entered into the Sample ID area by the analysis software without
further entries being necessary. If a different Sample ID is desired, the new Sample ID can be typed in manually.
Operation
57
Interrupting a Measurement
When the final measurement in a set of samples has been completed, or if there is a longer pause before the next
measurement, the user should carry out a Standard Clean in the Liquid Management system in addition to the
Ultra Fast Clean procedure that is automatically carried out between measurements (see “Cleaning Options”).
If multiple users have been created for the Cedex Software 2.2, log out of the software once the cleaning procedure has been completed to allow the next user access to the Cedex Analyzer.
The Cedex Sample Cup from the last measurement should remain attached to the sample port or left in the
Multi Sampler Tray in the DefaultCup position during the complete cleaning procedure. The cup should only
be removed when a new Cedex Sample Cup has been attached for the next measurement.
C
If the Cedex Analyzer is to be shut down after a set of measurements, or at the end of the day, the complete
Liquid Management system should be cleaned with an LM Shutdown procedure to maximize the life-span of
the Cedex Analyzer and guarantee optimal performance. The entire Liquid Management system is rinsed with
distilled or de-ionized water during the LM Shutdown, and the Trypan Blue is then pumped out of the capillary
(see “Carrying out an LM Shutdown and HW Shutdown”).
3.4
An orange EMERGENCY STOP button is located on the left-hand side of the Measurement window and can
be activated during the measuring procedure to interrupt the analysis process. If the EMERGENCY STOP is
selected, an error message will appear asking, “Do you want to cancel the process?”. Click on Yes to stop to stop
and abort the process immediately. Click on No to put the process on hold.
If Yes is selected, the EMERGENCY STOP button will change to read Unlock Queue. The system must be
unlocked by clicking on this button before more measurements can be run. If No is selected, the EMERGENCY
STOP button will change to read Resume. Click on this button to resume the measurement process.
Only use the Emergency Stop button in a case of emergency. Actual measurement data may be lost.
58
Working with the Multi Sampler
4
Moving parts of the Multi Sampler may cause hand injuries. The Multi Sampler needle may cause
injuries during operation. Never use the Cedex Analyzer without the protective cover in place for the Multi
Sampler.
The Multi Sampler is an accessory device for the Cedex Analyzer (see Figure 42 and Figure 43). The Multi
Sampler can convey up to 20 cell suspension samples in sequence to the Cedex System for analysis. Once the
samples have been loaded in the Multi Sample Tray and the analysis parameters for each sample have been set,
the samples are automatically delivered to the Cedex System and analyzed.

The position of the Cedex Sample Cup used for the Prime, LM Shutdown, calibration and cleaning routines is
called the DefaultCup. This sample cup does not differ from the usual Cedex Sample Cups. The standard
(default) position for the DefaultCup is position 1 of the Multi Sample Tray. The 20 numbered positions are
clearly marked directly on the Multi Sample Tray.
An empty Cedex Sample Cup must be manually placed in the position set for the DefaultCup before running
LM Shutdown, focus adjustment, Prime and all cleaning routines.
The position in which the DefaultCup is placed can be changed. See “Modifying the Standard Setting for the Multi
Sampler DefaultCup”). The position of the DefaultCup does not influence measurements. All 20 positions on
the Multi Sample Tray can be used for measurements. However, should a sample be present in the DefaultCup
position during Prime, LM Shutdown, focus adjustment or any cleaning routines, it can no longer be used for
a measurement.

Preparing the Measurement
4.2
Preparing the Measurement
4.2.1.
Using the Multi Sample Tray
Fill the appropriate volume of samples into Cedex Sample Cups (maximum 20) and place them on the Multi
Sample Tray according to the desired sequence. Gently insert the tray into the notch until the automatic tray
rope starts pulling it in.
As a safety precaution, leave all of the empty Cedex Sample Cups in the Multi Sample Tray after the
measurements have been completed.
4.2.2.
Ejecting the Multi Sample Tray
The Multi Sample Tray can be ejected by gently pushing on the tray only when the system is idle. The tray
cannot be ejected if the system is moving or the needle is down in a cup.
If a problem occurs with the system when the needle is down (see, for example, “Disruption of Measurements”),
restart the Hardware Management to render the tray ejectable again (see “Carrying out an LM Shutdown
and HW Shutdown”). In some cases it may be necessary to restart the Cedex Software 2.2 and Analyzer.
4.2.3.
C
Performing a Prime
The Prime and HW Startup are performed as usual in the Liquid Management window as described in
“Performing a HW Startup and Prime”. An empty Cedex Sample Cup must be placed in the DefaultCup position
(default position 1) of the Multi Sample Tray when running a Prime.
4.3
Carrying out Measurements with the Multi Sampler
Before carrying out measurements, ensure that the system is operational as described in “Checking the Analyzer”.
4.3.1.
The Multi Run Data Entry Window
Click on the Multi Run button in the Shortcuts area of the Cedex Control Center or select Multi Run in the
Measurements menu. The Multi Run window will appear, and entries for sample data and parameters for the
analysis process are entered via this window (see Figure 44).
In addition to the entry columns for ReactorID, SampleID, Cell Type, Dilution and Precision (see “Opening
the Measurement window and specifying the Operating Mode and Sample Data” for more details), there are also
columns for Status and CupNr. The CupNr column shows the sample cup position on the Multi Sample Tray.
The Status column displays the state of the sample before, during and at the end of a measurement.
Operation
61
4.3.2.
Preparing for Multiple Measurements in the Multi Run Window
The Multi Run window automatically displays all 20 possible sample cup positions. To set up and carry out
multiple measurements with the Multi Run do the following:
C
1
Transfer 1000 µl of a cell suspension sample into Cedex Sample Cups and place the cups in the desired
locations on the Multi Sample Tray.
2
Click anywhere in the row of the MultiRun Measurements Preparation area that corresponds to the
location of a Cedex Sample Cup containing a sample. The row will be converted to edit mode, and the
sample and process parameters for the measurement can be defined (see “Opening the Measurement
window and specifying the Operating Mode and Sample Data” and Figure 44).
3
Enter the desired sample data and parameters for the sample (see “Defining the Measurement and Analysis
(Process) Parameters”).
4
Enter a comment in the field Comment, if desired.
5
Repeat steps 2 – 4 for the remaining samples to be measured.
6
The rows in which entries are in the process of being filled out will remain in edit mode. To clear the entire
list of entries and start with a new list, click on the Clear List button on the right-hand side of the Multi
Run window.
■
Measurement of up to 20 samples in a row leads to prolonged incubation (up to 90 minutes) of cells at room
temperature. Tests in our lab using several different cell lines (CHO-K1 and several hybridoma cell lines)
showed no noteworthy influence of the prolonged incubation times on the measurement results. However,
this result may not necessarily apply to all cell lines available on the market. We, therefore, recommend
testing especially sensitive cell lines in advance to determine the number of samples that can be measured in
a row without affecting the cells.

4.3.3.
Activating Sample Rows and Starting the Measurement
After all sample information has been entered in the Multi Run preparation area, the samples can be activated
and, thus, added to the process queue. To activate samples and start the measurement, do the following:
1
Activate the status of each sample row by double clicking in the Status field of the row to be activated. The
row appears pale blue, and further modifications of sample information is impossible. Return to the Edit
status by double clicking on the Status area of the sample row to allow for further changes, if required.
2
Alternatively, all samples can be activated or deactivated simultaneously by double clicking on the word
Status in the column heading at the top of the Multi Run preparation area. Confirm the safety query with
Yes to accept the modification.
3
After some or all rows have been activated, click on the Start button on the right-hand side of the Multi Run
window to start the analysis of the activated measurements.
■
When measuring begins, the row of the sample being measured will be highlighted in yellow, and the progress
of the measurement will be tracked in the status column. When a measurement is finished, the row will be
highlighted in green and status column will indicate Done. In addition, the estimated time required for the
measurement is shown in the Estimated time remaining field.
Images taken of the sample are displayed in the upper right-hand corner of the Multi Run window during the
measurement. In addition, results for Total Cell Concentration, Viable Cell Concentration and Viability are
displayed in the upper left-hand corner of the Multi Run window during and after a measurement has finished.
C
Before, during and after measuring, the Status column can display the following information (see Figure 44,
above and Figure 45):
Edit:
Indicates that sample data is actively open for editing and is in the process of being edited. Sample
data in edit mode has not yet been added to the process queue, and samples placed in positions
in edit mode will not be analyzed when the Multi Run is started. Rows in edit mode are white.
Active:
Indicates that the sample is ready for analysis, which starts automatically once the Start button is
pressed. Rows in active mode are highlighted light blue.
Scheduled:
All rows marked as active will be added to the process queue and converted to scheduled mode
after pressing the Start button. Rows marked as edit will remain in edit mode.
Prepare:
Indicates that the system is preparing to measure the sample marked with this status. The row is
highlighted in yellow.
Measure:
Indicates that the system is in the middle of carrying out a measurement of the sample marked
with this status. The row is highlighted in yellow.
Cleaning:
Indicates that the system is carrying out the cleaning routine after a completion of a measurement. The row is highlighted in yellow.
Done:
indicates that measurement and analysis of a sample marked with this status has been completed
successfully. The row is highlighted in green.
Failed:
The measurement of this cup has failed.
Aborted:
The measurement of this cup has been aborted by the user.
No Cup:
There was no cup at this position in the multi sampler when it was ready for measurement.
Blocked:
The lift was blocked when the cup should have been measured.
The status of a particular measurement is tracked in the Status column. The Errors and messages window gives
a list of each step completed and any errors that may have occurred.
Operation
63
C
Figure 45: Multi Run window during measurement
Only samples that have the status of active or scheduled will be measured. Samples that are in edit mode
have not yet been added to the process queue and will not be measured until they have been activated.
If an automated cleaning has been scheduled via the Scheduler function, the cleaning routine has a lower
priority than scheduled measurements and will be added to the process queue after all activated (status:
active or scheduled) measurements have been carried out (see “Scheduling Automatic Cleaning Routines”
for more information about automating cleaning routines). Note that measurement information placed in
the Multi Run preparation area that have the status of edit are not added to the queue! Therefore, if a Cedex
Sample Cup containing a sample is added to the Multi Sample Tray in the DefaultCup position, and the row
for that sample is left in edit mode, the cup will be used for a cleaning routine should one be scheduled to be
carried out at that time. It is therefore critical to ensure that a Cedex Sample Cup containing a sample to be
measured is never placed in the DefaultCup position on Multi Sample tray and left in edit mode during a
Multi Run. Samples placed in the DefaultCup position for measurement should be immediately set to active
or scheduled in order to be added to the process queue and, thus, have precedence over all scheduled cleaning
routines.
4.3.4.
Adding Measurements to the List while Measurements are Running
Sample rows in which data has not yet been entered can be filled out at any time while the Multi Run is running.
In addition, sample rows containing finished measurements (status: done) can be cleared and prepared for a
new measurement by double-clicking in the Status field of the row with the finished measurement. Sample data
for a measurement cannot be modified after that measurement has begun.
64
Interrupting a Multi Run
4.3.5.
Modifying Data Entry, Changing Samples
Information about the operation and process parameters for samples that have not yet been analyzed can be
modified during the run. To modify information of measurements that are in active or schedule mode but have
not yet been started, do the following:
1
Double-click on the Status field of the measurement to be modified. The status field will indicate that the
sample is in edit mode.
2
Make desired changes to the measurement.
3
Double-click on the Status field to re-activate the measurement (status: active or scheduled).
■
Wait until the Multi Sample Tray has stopped moving before changing the samples!
4.3.6.
Non-Linear Measurements in a Sample Series
Measurements of activated samples are always done in a linear fashion following a sequence of 1 – 20. If samples
need to be analyzed individually and not in the usual linear ascending order of 1 – 20, the samples to be analyzed
later should be inactivated and remain in the Edit status for the meantime. When all active samples in the
sample tray are completed, subsequent measurements with the newly activated samples can begin.
4.4
C
Interrupting a Multi Run
The Start button will switch to a Stop button after a Multi Run has started. Click on the Stop button to pause or
stop the Multi Run. If a measurement is being carried out when the Stop button is pressed, that measurement
will be completed. All scheduled measurements (status: scheduled) will switch to active mode, and the Stop
button will revert to Start. Click on the Start button again to continue analysis of activated measurements.
4.5
Disruption of Measurements
Error messages may appear if a sample can’t be run. For example:
If a Cedex Sample Cup is not available in its position on the Multi Sample Tray during measurements, then
the No Cup message will appear.
If the Multi Sample Tray is not inserted or not inserted correctly, then the Tray not inserted message will
appear.
Some errors may block the analysis of the rest of the measurements. The level of error that should stop the
analysis of all samples can be determined using the Error Level drop-down list at the top of the Multi Run
window. The options for the level of error that will stop the analysis are:
Fatal: Only errors involving a system / hardware crash, when functionality is not available, will stop analysis.
Critical: Data loss or any other error that results in an invalid measurement will stop the analysis.
Error: Errors that do not result in an invalid measurement will stop the analysis.
Warning: Warning messages with information for the user will stop the analysis.
Message: Any message will stop the analysis.

Viewing a Cell Image Using the Image View Window
It is possible to see which cells were marked viable and dead cells by the analysis software via the Image View
window. The user can thus get a sense of how cell shapes and clusters have been evaluated by the software. The
Cedex Software 2.2 offers various options for optimizing measurement results by adjusting the Operator used
for the analysis. Thus, the image analysis Operator can be adjusted for abnormal cell culture images or for
specific internal counting strategies. For more information about adjusting the image analysis, see “Adjustment
of the Image Analysis using the Live Operator”.
The Image View offers the following information and options:
Viable Cells: number of viable cells.
Dead Cells: number of dead cells.
Show Circles check-box: switches on/off the marking of cells recognized as living or dead. Viable cells
are marked with a uniform green circle and dead cells are marked with a red circle. The circle diameter
corresponds to the cell diameter. Objects are marked with a blue circle.

Excluding Images from the Evaluation Process/Including Excluded Images
Images can be excluded from analysis by the user. Also, images that have been excluded automatically by the
analysis software (due to, for example, excessive bubbles or dirt) can be included in the result analysis, if desired.
Exclusion and inclusion of images for a particular measurement are done via the check-box in the Excluded
column in the Result Data area of the Measurement window.
If there is a check in the Valid check-box, the image is considered valid, which means that the cell image has
been included in the calculation process. The user can choose to manually exclude the image by clicking on the
checkbox in the Excluded column for the selected image. The image will still be marked as Valid, but will also
be excluded from the calculation of results.
No check in the Valid check box means that the cell image is not considered valid and has been automatically
excluded from the calculation process. In that case, a check-mark will automatically appear in the Excluded
column. To include an image that was excluded by the software, click away the check-mark in the Excluded
column. The image will still be marked as invalid via the lack of check-mark in the Valid check-box, but will be
included in the calculation of results.

Using the Measurement List
2
Data from measurements that have been carried out and stored in the database can be accessed via the
Measurement List window. Open the Measurement List window by either clicking on the List button in the
Shortcuts area of the Cedex Control Center or by selecting Measurement List in the Measurements menu at
the top of the Control Center. Measurements are stored in the order in which they were carried out, with the
most recent measurement placed at the top of the list.
Two types of information can be displayed in the list of measurements: information about sample and process
parameters and information about some results. If there is no check in the Show measurement results box at
the bottom left-hand corner of the window, sample and process parameters for measurements are displayed
(see Figure 52, below).

From section,) or that were run within the dates specified in the Process Date From section, will be displayed
in the measurement list in the bottom half of the window.
■
It is possible to select measurements with regard to both sample drawing date and process date. If the desired
dates for both the sample drawing dates and process dates are selected, only those measurements that meet all
4 date criteria will be displayed when the Find button is clicked on.
Measurements can also be searched for based on Reactor ID and/or Sample ID by filling in the information in
these sections of the Filter By area. In addition, measurements can be searched for based on user by typing in
the user name in the User section, by work area (using the drop-down menu in the Workarea section), by data
set (in the DataSet area) and by Cell Type (using the drop-down menu in the Cell Type section).
If a measurement has been reprocessed, the original and all reprocessed versions of the measurement will be
listed. The data set version of a particular measurement that has been selected as the Effective data set will
have a check in the check-box of the DSEffective column. The original data set of a particular measurement
will have a check in the check in the check-box of the DSOriginal column (see “Effective Data Sets”).

In addition to displaying the overall analysis values, the Cedex Software 2.2 can also display graphic diagrams
of the results. These diagrams can be viewed after the analysis is finished by clicking on the Diagrams button in
the Result Data area of the Measurement window. When the Diagrams button has been selected, the Diagram
window will open. 4 different histograms are available: Aggregate Histogram, Cell Diameter Histogram,
Compact Histogram, and Measurement Statistics. Click on the respective button to open the desired diagram.
The Object Diameter Histogram function is present, but no data is delivered by the presently available Cell
Type.
All the results represented in the diagrams are based on valid images accepted for evaluation. This means that
individual images may be sorted out due poor quality (e.g., bubbles, dirt particles, etc) in the interest of an
accurate measurement result. This is done automatically by the analysis software or manually by the user (see
“Excluding Images from the Evaluation Process/Including Excluded Images”).

Aggregate Histogram
4.2
Aggregate Histogram
The Cedex Analyzer offers an evaluation of aggregates in cell cultures. Click on the Aggregate Histogram
button in the Histograms window to open the corresponding histogram window.
The Aggregate Histogram shows the number of cells in the cell culture found in aggregates, as well as how
many cells each aggregate is composed of. Both the actual cell number and the percentage distribution can be
displayed.
D
Figure 54: The Aggregate Histogram, detailed view (divided into living and dead cells), here: (absolute) number of cells
The Number of Cells [#] identified is displayed on the y-axis and at the top of the bars. The Aggregate Size, in
terms of the number of cells per aggregate, is given on the x-axis. Figure 54 shows, for example, that 148 living
and 40 dead cells of all identified cells were found in aggregates of two cells.
80
Aggregate Histogram
The percentages can be displayed using the percent button.
Figure 55: The Aggregate Histogram, detailed view (divided into living and dead cells), here: percentage distribution of cells
The percentage of cells [%] found in aggregates compared to the total live or dead cell count is displayed on the
y-axis. The aggregate size, in terms of the number of cells per aggregate, is given on the x-axis. Figure 55 shows,
for example, that 3.66% of all living cells and 7.29% of all dead cells are found in aggregates of two cells.
The Total Cell Count (living and dead cells combined) per aggregate is mapped in the histogram using the total

Object Diameter Histogram
4.3.1.
Defining Diameter Intervals in the Diameter Histogram
The Cell Diameter Histogram has three sliders that can define separate diameter intervals. This allows for
dividing a diameter histogram into a maximum of four parts. The sliders can be activated by clicking on the
corresponding boxes and moving the sliders to the desired positions. One can also define the margins of the
intervals by entering the numerical values on the left hand side of each slider.
The borders of the first interval are defined by the minimum value and the first numerical value entered. The
next two values define the upper borders of the second and third intervals. The fourth interval is defined by the
upper border of the third interval and the maximum value.
The number of viable cells, their percentage of the total viable cell number and the viable cell concentrations
[×105 cells /ml] are listed in a table for each of the individual intervals.The intervals set in the Cell Diameter
histogram can be saved for future reference. In addition, the default intervals can be automatically set for all
measurements via the User Preferences (see “Specifying Default Measurement Parameters”).
4.4
Object Diameter Histogram
Clicking on the Object Diameter Histogram button will bring up the Object Diameter Histogram. Analogous
to the representation of the diameter of the living cells, the diameter of all recognized objects such as cells, debris,
air bubbles and viable and dead cell aggregates may be displayed in this histogram depending on whether the
information is provided by the image analysis software.
The default image analysis software (Cell Type: Std. Size (V5.00)) delivered with the Cedex Analyzer does
not provide any detailed information about objects. Therefore, clicking on the Object Diameter Histogram
button will result in a message that there is nothing to display, and nothing will be shown in the diagram.

Compactness Histogram
4.5
Compactness Histogram
The ratio between the cell circumference and the cell area is based on an ideal sphere (4␲), which is equivalent
to the value >1< on the abscissa of the Cell Compactness Histogram. The extent of variation between the
cell shapes and an ideal sphere is reflected in values being greater than 1. The shape of a cell is known as the
Compactness. Click on the Compactness Histogram button to display a diagram that compares viable (!) cell
shapes to that of an ideal sphere.
If a significant number of cells (ordinate) have a high value, this could indicate improper handling of a sample.
The Compact Histogram can be used to check the state of the cell culture, e.g., if the stirring speed is too high
or nutrient composition is incorrect.

representation can be enlarged or scaled down again with the use of the mouse (see “Enlarging the Diagrams”).
5.2.2.
Fitting to the Lowest Common Value
The Fit lowest common value button enables automatic shifting of the zero-point of single measurement series
to each other. The following can be selected:
Viable Cell Density
Dead Cell Density
Total Cell Density
By means of this function, the zero-point of each series will automatically be shifted on the x-axis, in order to be
able to better compare the measurement series to each other. The lowest common value of all the measurement
series is automatically determined, and the graphs in the diagram are shifted to each other so that the lowest
common value falls on the x-axis at the same point. While doing so, the left-most point of the graph of all the
measurement points is set at value 0.
D
5.2.3.
Measurement Series Offset
In the graph, measurement series are automatically displayed such that all measurement series begin at time
0. The different measurement series can, however, be best compared to each other when the beginning of the
exponential growth phase (log phase) starts at the same time. Therefore, it is possible to shift the curves in the
diagram by changing the offset for each series.
A button in the Offset column of the Data Series area displays the offset set by the user (the button displays 0
[h], if an offset was not set). Clicking on this button opens the Measurement Offset window. The measurement
series offset can be then manually shifted in this window.
Figure 65: The Measurement Offset window
The offset can be separately entered for each of the five measurement series by clicking the button with the
corresponding number of the measurement series. Large time differences can be entered in days [d], small
ones in hours [h] by clicking on the appropriate buttons [d]/[h]. The offset can be set by selecting the desired
series number (colored boxes) and then moving the slider to the desired offset. Using the slider will cause an
immediate shift of the measurement series in the diagram so that it can be immediately seen where the best
position for a series is in the diagram.
The smallest time unit that can be set is 0.10 hours. The OK button confirms the offset values in the graphics.

The following system functions are generally only available to the Administrator and/or Superuser:
Administration of user accounts
Password management and assigning workareas
Adjustment of the image analysis
Securing data
7.1
The user usually has limited access rights. All administration rights relating to user accounts, i.e., creating,
deleting, modifying and delegating rights, should remain exclusively with the Administrator.
All administration of user accounts and rights management is done in the User Rights Management area. To
open the User Rights Management area, click on the Setup menu in the Cedex Control Center and select User
and Rights Management.
The User Rights Management window is structured with menus and sub-menus similar to the directories in
Windows Explorer (see Figure 70). The distinction between functions, roles, users and groups, which is mainly
connected to the delegation of rights, is explained in the appropriate sections of this chapter. Password settings
can also be configured in this area.
7.1.1.
Creating User Accounts

Software
101
7.1.2.
Assigning Access Rights
The user is normally denied access rights to certain areas, e.g., administration of user accounts and sensitive
system functions (focus adjustment, creating SST-Checkpoints etc.). The user, therefore, cannot access all of the
menus on the Control Center after login.
Access rights can be modified at any time by the Administrator. Rights are generalized in user roles that can
comprise a single access right or a set of access rights. To grant rights you will need to assign one or more user
roles to a user. The following user roles are available after installation of the software:
Administrator
Production Staff
Research Staff
Superuser
Support
By default, the pre-installed Production Staff, Research Staff and Support roles have no functions assigned to
them. More detailed information about creating functions for each pre-set user role, as well as editing existing
functions and creating new user roles, can be found under “Creating and Editing User roles”.
D
Follow the instructions below to assign rights to a user account:
1
Click on the Setup menu in the Cedex Control Center.
2
Click on User and Rights Management, and the User Rights Management window will appear.

7.1.3.
Creating user groups
IIt is possible to generalize one or more user accounts in user groups. Instead of assigning rights to a single user,
a user role or a set of user roles can be assigned to a user group. The whole user group, therefore, receives all
access rights that have been assigned to the user roles.
To create a user group and add user accounts proceed as follows:
1
In the User Rights Management area right click on the User Groups main menu and click on Create
new user group.
2
A name for the new group can be entered in the User Group window.
3
Click on OK to add user group to User Groups list.
4
Open the All Users main menu and drag from it the desired user account into the appropriate user group
sub-menu. The user is added to the user group and receives all access rights assigned to this group. A user
can be added to one or more user groups.
■
7.1.4.
Editing and Deleting User Accounts
The first name, last name and username of a user account can be edited if, for example, an existing user is to be
replaced by a new user with identical access rights. A user account can also be deleted in the editing area.
Proceed as follows to edit a user account:
1

as a user name that has been deleted. Measurements that have been run under a user name that has been
deleted are still available for viewing.
Software
103
7.1.5.
Creating and Editing User roles
Rights are generalized in user roles that comprise a single access right or a set of access rights. In the User
Rights Management area, access rights are declared as functions. It is necessary to determine the different
responsibilities for the different roles and, therefore, functions they should have access to.
Five standard user roles are pre-installed by the software. All of the roles are suggested roles that could be used
for setting up specific distribution of access rights:
Administrator: The administrator is allowed to use all administrative functions of the system. He is not
allowed to use any operational functions.
Production staff: It is intended for members of the production staff who are only allowed to use specific
operational functions depending on company policies (i.e., execute measurements, execute an SST, change
consumables).
Research staff: Members of the research staff who could be allowed to use all operational functions of the
system.
Superuser: The Superuser is allowed to use all operational functions of the system mainly for maintenance
purposes.
Support: Support of the Cedex System by Roche technical services requires access to all operational functions
similar to the Superuser role.
D
Access to the System Options should be restricted to the Administrator, Superuser and Support. All options
necessary for a user to modify his workplace according to his needs can be found under User Preferences.
Only selected users should be authorized to edit SST-Checkpoints. See “Creating SST checkpoints” for further
information.
Follow the instructions below to create a new user role:
1
In the User Rights Management window right click on the All Roles main menu and then click on Create
new role.
2
A name for the new role can be entered in the Role window.
3
Click on OK to add the new user role to the All Roles list.

The System Options
The System Options area, in which system parameters are configured, is located in the Setup menu on the
Cedex Control Center. Only those users who have been given access to the System Options function (for
example the Superuser and Support) can change system parameters.
Setting system parameters includes several changes and modifications, some of which are explained in detail
in the sections below. The parameters are organized based on the application areas that are affected (e.g.,
Measurement, Hardware, Data Exchange).
See “System Options and User Preferences” in the Appendix for a detailed description of all of the System
Options.
The Cedex Software 2.2 may need to be restarted in order for changes in the Systems Options to take effect.
All elements in the System Options that have not been explicitly described in this Operator’s Guide must not
be changed without prior arrangement Roche Diagnostics GmbH. In all cases, contact must be made with the
local Roche technical services before any such changes are made.
Access to the Systems Options should be restricted to only the users who are responsible for maintenance of
the system! Changing default values in the Systems Options window can have an adverse effect on the system
and measurement results!
7.4.1.
Automatically Start the Hardware Management
If the AutomaticallyStartHardware parameter is active (entry “1” in the Value column) the hardware
management will automatically be initialized when the software is started. To turn off this function, set the
value to “0” in the Value column.
7.4.2.
D
Modifying the Standard Setting for the Multi Sampler DefaultCup
The default setting for the Multi Sampler DefaultCup (Cedex Sample Cup used for Prime, LM ShutDown,
focus calibration and all cleaning routines) is position 1 on the Multi Sample tray. The default position can be
changed to any other position. To change the position for the DefaultCup location, do the following:
1
Open the System Options window and click on the General tab.
2
Look for the parameter DefaultCupPosition. The number entered in the Value column will determine the
position for the DefaultCup on the multi sampler tray.
3
Click on Save to confirm the change.
■
The position chosen for the Multi Sampler DefaultCup does not influence measurements. All 20 positions on
the sampler plate can be used for measurements. Should a sample be present in the DefaultCup position during
Prime, LM ShutDown, calibration or any cleaning routines, it can no longer be used for measurements.

7.4.3.
Turning off Automatic Incrementation of Sample Cup Position
In the case of single measurements run via the Measurement window on a Cedex Analyzer with a Multi Sampler
attached, the software will automatically incrementally increase the sample cup position number with each new
measurement. To switch off this feature, do the following:
1
Open the Systems Options window and click on the Measurement tab.
2
Look for the parameter SuggestNextCupPosition.
3
Select 0 from the drop-down menu to turn off the feature.
4
Click on Save to confirm the change.
■
When 0 has been selected, the suggested cup position will always be the same.
7.4.4.
D
Error Level Displayed to Users
Errors in the software and hardware will be displayed to the user in the form of an error message. The
level of error that will result in the display of an error message depends on the setting of the parameter
ErrorLevelDisplayToUser in the General tab of the Systems Options window. The following levels are available:
Level 1 (Fatal): fatal error, system/hardware crash.
Level 2 (Critical): Error as a result of invalid measurement.
Level 3 (Error): Error, but the result does not cause an invalid measurement.
Level 4 (Warning): Information for user.
If, for example, the ErrorLevelDisplayToUser is set at Level 1, only error messages regarding system or hardware
crashes will be displayed to users. The factory-installed default for the ErrorLevelDisplayToUser is set at Level
3 (Error).
7.4.5.
Liquid Container Configuration
In the Liquid Container Configuration area, the minimum and maximum liquid levels for reagent and waste
containers can be set. To open the Liquid Container Configuration window proceed as follows:
1
Click on the Master Data menu on the Cedex Control Center.
2
Click on Liquid Container Configuration and the window will appear.
■
Maximum and minimum volumes can be defined using this window. When standard sized containers are used,
it is not advisable to change default settings for the Min volume and Max volume.
It is also possible to define a Warn Level and a Lock Level. The standard default for the Warn Level is 6. This
means that a warning message will appear if the amount of reagents left is 6 ml or less. The standard setting for
the Lock Level is 3, which means that the system will be locked (i.e., no further measurements will be possible)
if there are only 3 ml left.
The settings for the Warn Level and Lock Level can be changed. Saving changes will immediately update the
estimation of the number of remaining measurements.
108
Adjustment of the Image Analysis using the Live Operator
7.4.6.
Disabling the Reagent Control
The Reagent Control function keeps track of the amount of reagents used and notifies the user when the levels
are running low. The function can be disabled in the General tab of the System Options window. The Reagent
Control function is enabled when the value for the DisableReagentControl entry is set to “0”. To disable the
function, set the value to “1”.
7.4.7.
Default Settings
In general, research or production staff users are not assigned access rights to the System Options window in
which default settings that apply to the whole system can be configured. However, some parameters needed to
customize the individual workplace (e.g., definition of the default settings for certain measurement parameters)
can be found under User Preferences (see “User Preferences”).
7.5
The Cell Type (operator) selected for a measurement takes care of the image evaluation. Roche Diagnostics
GmbH has put in one pre-setting:
Std. Size (V5.00) for normal-sized cells with a diameter of about 12 µm, e.g., HB58
Individual adjustments of the operator can be helpful or necessary for cell cultures that, for instance, have an
unusual optical appearance or for a counting strategy that deviates from the Cedex Analyzer (e.g., counting
aggregates differently).
D
Adjustment of the operator is referred to as creating a new Cell Type. A new Cell Type can be created or an
already existing Cell Type can be re-adjusted. This can be done with the help of eight parameters that influence
the way in which an image is evaluated.
Each of these parameters directly influences the image processing strategy and, hence, the measurement results.
In the available software version, an algorithm with the pre-setting mentioned above is available. The parameters
of the factory installed pre-setting are overwritable.
For data safety reasons the parameters of the factory installed pre-setting should not be altered. Since original
settings are overwritable, caution ought to be advised for all authorized users.
7.5.1.
Description of the Cell Type List and Live Operator
The Live Operator window, in which Cell Types can be created and modified, is accessed in two ways:
Via the Measurement window in the View mode.

7.5.8.
Description of the Individual Operator Parameters
LivingAppearance (Living Cells‘ Appearance)
Range: [-20, 20], Default: 0, Unit: [absolute measure].
This parameter influences the recognition of living cells. When the value of this parameter is set high, contrastweak objects are also counted as living cells provided they additionally fulfill the size criterion. The lower this
value is set, the more contrast an object must have for it to be counted as a viable cell.
If the value is changed to positive, shadowy and greyish objects are increasingly counted as living cells. Such a
change can be sensible if, for example, the optical image shows little contrast due to the structure of the medium
or of the cells in the medium.
D
In standard situations a change of this parameter can result in the labeling of debris as cells!
DeadSize (Dead Cells’ Size)
Range [40, 250], Default 110, Unit [µm²].
Defines the minimum cross-sectional area of a particle in µm². Increasing this value means that fewer particles
will be recognized as dead cells.
DeadAppearance (Dead Cells’ Appearance)
Range [-10, 10], Default 0, Unit [absolute measure].
This parameter influences the recognition of dead cells. If the value is set high, contrast-weak objects are also
counted as dead cells as long as they additionally fulfill the size criterion. The lower this value is set, the sharper
the contrast an object must have in order to be counted as a dead cell.
DeadAggregateApp (Dead Cells’ Aggregate Appearance)
Range [-10, 10], Default 0, Unit [absolute measure].
Defines the automatic evaluation of a dead cell aggregate (cluster).The cross-sectional area of dead cell
aggregates are automatically partitioned into single cells. Increasing this value means that there are more single
cells determined in the aggregate.
Software
115
DeadAggregateMax (Dead Cells’ Aggregate Maximum)
Defines the maximum cross-sectional area of a dead cell aggregate (cluster). The dead cell aggregate area within
this range is automatically partitioned into single cells. Any aggregate larger than the specified maximum area
is not taken into account.
DeadAggregateMin (Dead Cells’ Aggregate Minimum)
Defines the minimum cross-sectional area of a dead cell aggregate (cluster). When this size is reached, it is then
automatically partitioned into single cells.
MinPollutionArea (Minimum Pollution Area)
Defines the minimum cross-sectional area of the pollution size e.g., debris particles, air bubbles etc. Any
pollution size larger than the specified minimum area results in the entire image being excluded.
D
116
BorderWidth [µm]
Range: [0, 20], Default: 7, Unit: [pixels].
The border frame around the image not used for evaluation.
The use of the sliders, especially in combination, can lead to unexpected results.
Archiving Data
7.6
Archiving Data
The objective of the archive function is to secure measurement data by exporting it to external storage media.
Measurement data must be secured at regular intervals and thereafter deleted from the Cedex Analyzer
Measurement List in order to ensure enough storage capacity on the Cedex Analyzer Control Unit. All data
from a single or a set of measurements, or optionally only the images, can be deleted from the database once the
measurement or measurements have been archived.
Archiving should only be carried out by the administrator and selected users.
Measurement data can later be restored from the archive, but restoring the data will only be possible using the
Cedex System Database the data has been archived from. All data should also be backed up on a regular basis.

Cleaning and Maintenance Check List
1
Cleaning and Maintenance Check List
This checklist shows when each cleaning and maintenance routine should be done.
Carry out these routines on a daily basis:
LM Shutdown: always after the last measurement and before a Cedex Analyzer shutdown.
If a Prime has been scheduled to be automatically run the next morning, the Hardware Management should
not be shut down as a Prime can only be run when the Hardware Management is active (see “Scheduling
Automatic Cleaning Routines”).
Standard Clean: after the final measurement of a set of samples or before a longer pause between measurements.
Chamber Clean 2: at least twice a day.
Carry out this routine on a weekly basis:
Intensive Clean
Change of Trypan Blue solution
The following routine should be done every week for users that refill reagents themselves:
Empty the reagent containers and the waste container.
Thoroughly clean the containers.
Refill the reagent containers (see “Refilling Containers Individually“)
Carry out this routine on a bi-monthly basis:
Special Intensive Clean: at least twice a month with 0.1 – 1 N HCl instead of detergent.
E
120
Carry out these routines on a regular basis (once a week or after 250 measurements):
Clean the casing, Reagent Tray, Multi Sampler housing (if installed) and Reagent Port by wiping down with
70% alcohol and a lint-free cloth.
Run a focus adjustment of the analyzer every month or after any change of position or vibration of the
measurement system.
Scheduling Automatic Cleaning Routines
2
Scheduling Automatic Cleaning Routines
Routine cleaning operations can be scheduled so that they are automatically included in the process queue.
Depending on the settings, the cleaning operations are automatically run at a pre-defined time or after certain
events.
To create a new entry in the schedule, proceed as follows:
1
Select Scheduling from the Functions menu in the Control Center. The Schedule window will appear.
2
Click on New to open the Schedule process window.
3

(e.g., Fast Clean) and Hardware Management routines (e.g., Prime, LM Shutdown).
4
Select one of the three options with regard to the time schedule for an automatic process:
Every: The process is automatically run at the selected interval of one or more days. A specific time of the
day for operation can also be set.
After an event: The process is automatically run after system start-up or after a selectable number of
measurements.
After certain time of inactivity: A certain amount of time of inactivity can be defined after which the
process is run automatically. If the only once box is checked, the scheduled process will only be run
once, even if there is another period of inactivity afterwards.
5
Click on Save to add the entry to the Schedule list. The Schedule process window will automatically close
and the Scheduling window will reappear showing the newly scheduled process in the list.
■
Scheduled processes can also be edited and deleted by highlighting the appropriate row in the Schedule window

window in which the process can be edited.
When scheduling an LM Shutdown or a Prime, it is important to ensure that the Hardware Management
is not shut down before the scheduled Prime or LM Shutdown is run (e.g., the hardware is shut down in the
evening before a scheduled Prime is to be performed in the morning). Prime and LM Shutdown can only be
executed if the Hardware Management is active.
E
121
Daily and Manual Maintenance and Cleaning Routines
Checking the Reagent Containers when Manually Refilling
3
The following cleaning and maintenance routines should be carried out on a regular basis or whenever necessary.
3.1
Checking the Reagent Containers when Manually Refilling
Empty reagent containers lead to wrong measurement results and can cause a dry run, thereby damaging the
syringe and the 8-way valve. Regular checks of the liquid level are done via the Reagent Kit Status window,
which is located under the Functions menu.
For safety reasons, the liquid level of the individual reagent containers, as well as the capillary positions,
should also be manually checked before each measurement and, if necessary, replaced or refilled. For detailed
information, see “Refilling Containers Individually“.
Cleaning the reagent containers when manually re-filling
All reagent containers must be thoroughly cleaned at regular intervals and rinsed with distilled or de-ionized
water. Impurities caused by dust or fluff must absolutely be avoided! The Trypan Blue is especially critical as it
can become contaminated with microorganisms. In the case of such contamination, exact measurements are no
longer possible. If the Trypan Blue solution is contaminated, intense areas may be visible in the image that will
make image analysis difficult or even impossible.
Replacing the reagents after 5 days is recommended. For detailed information, see “Refilling Containers
Individually“.
3.2
E
Cleaning Routines Carried out by the Liquid Management
The Liquid Management plays a key role in the Cedex Analyzer. It is necessary to Prime the system at the
beginning of the day, and to carry out an LM Shutdown prior to shut down of the system in the evening (see
“Carrying out an LM Shutdown and HW Shutdown”).
The Liquid Management automatically runs an Ultra Fast Clean routine after every sample measurement.
During the Ultra Fast Clean (approx. 30 seconds), the entire Liquid Management system, including capillary
tubes, flow chamber and sample port, are rinsed out thoroughly.
Manual cleaning routines can be carried out in the Cleaning window. To open the Cleaning window, click on
the Clean button in the Shortcuts area of the Control Center or select Cleaning routines in the Functions
menu (see Figure 76).
Figure 76: The Cleaning window of the analyzer
122
3.2.1.
Cleaning Options
The following cleaning routines can be run manually:
Fast Clean
Standard Clean
Intensive Clean
Chamber Clean 1
Chamber Clean 2
Fast Clean and Standard Clean involve the entire Liquid Management system including capillary tubes, flow
chamber and sample port. Therefore, always ensure that there is a Cedex Sample Cup attached to the sample
port to prevent flooding.
Fast Clean (with detergent, and distilled water for approx. 60 seconds)
The entire Liquid Management system is rinsed with distilled water, then with detergent and finally with
distilled water. Use this routine between measurements to remove dirt particles and air bubbles quickly from
the flow chamber.
Standard Clean (with cleaning solution, detergent, and distilled water for approx. 90 seconds)
The entire Liquid Management system is rinsed with distilled water, cleaning solution, detergent and finally
with distilled water again. This routine removes dirt particles and is used after measuring a set of samples or
before a longer pause.
Intensive Clean (with cleaning solution, detergent, and distilled water for approx. 20 minutes)
The flow chamber is thoroughly rinsed with distilled water + cleaning solution + distilled water + detergent
and finally distilled water. The detergent remains in the flow chamber for a longer period to work on resistant
particles.
The Intensive Clean routine is used on weekly basis to remove heavy and resistant contamination of the flow
chamber, capillaries tubes, syringe and 8-way valve. Even the smallest dirt particle attached to the glass wall
of the flow chamber can negatively influence a measurement. See also “Live View of the Flow Chamber”. If
measurement values within a sample measurement show large variations, this could indicate that the flow
chamber is soiled.
E
Intensive Clean with HCl
A special Intensive Clean is required twice per month for a thorough cleaning. For this cleaning, a solution of
0.1 – 1 N HCl is used instead of detergent.
1
Remove the Detergent container and replace it with an appropriate container with a 0.1 – 1 N HCl solution,
taking care that the capillary tube reaches far enough into the solution.
2
Start Prime.
3
Start Intensive Clean after Prime has ended.
4
Replace the HCl container with the Detergent container at the end of the Intensive Clean process.
5
Start Prime again.
6
Start Standard Clean after Prime has ended.
■
123
The Chamber Clean 1 and Chamber Clean 2 cleaning routines are only required for the flow chamber.
Chamber Clean 1 (with water for approx. 10 seconds)
The flow chamber is rinsed at high pressure with distilled or de-ionized water being drawn in through the
syringe. Use this routine to remove resistant protein aggregates, fluff particles or other obstructions from the
flow chamber.
Chamber Clean 2 (with water, detergent, and air for approx. 30 seconds)
This routine is more intense than the Chamber Clean 1 procedure. Once the flow chamber is rinsed with water
and detergent, the remaining liquid in the capillary tubes between the syringe and valve head is drawn through
the flow chamber and then pressed back again with compressed air.
Use this routine twice daily to remove resistant protein aggregates, fluff particles or other obstructions from the
flow chamber.
3.2.2.
The Hardware Management Window
Prime and LM Shutdown can be executed in this window. An LM Shutdown must be carried out after the last
measurement has been run and before shutting down the Cedex Software 2.2. The Liquid Management system
is then prepared for an extended pause, i.e., overnight or weekend.
An LM Shutdown is automatically preceded by a Standard Clean routine. The 8-way valve is then rinsed with
distilled or de-ionized water to prevent crystallization, and compressed air finally presses the Trypan Blue
solution back into its container (see “Carrying out an LM Shutdown and HW Shutdown”).
3.2.3.
E
Carrying out a Cleaning Routine
The different cleaning routines always have the same starting procedure. Ensure that there is always a Cedex
Sample Cup attached to the single sample port or placed in the DefaultCup position on the Multi Sample tray.
1
Click on the Clean button in the Shortcuts area of the Control Center or else select Cleaning Routines
in the Functions menu. The Cleaning window will open.
2
Click on the appropriate button (e.g., Fast Clean) to automatically start the cleaning routine.
■
The Cedex Analyzer is blocked during the cleaning routine, and the duration is continuously displayed in the

3.2.4.
Interrupting/Terminating a Cleaning Routine
Use the EMERGENCY STOP button to interrupt the cleaning routine immediately if any leaks are detected in
the Liquid Management system, even in the case of an Ultra Fast Clean being carried out automatically.
The Intensive Clean procedure can be interrupted to shorten the long detergent phase in the flow chamber.
Click on the Cancel button, which is only activated during the long detergent phase, in the Liquid Management
window.
3.3
Live View of the Flow Chamber
The Live View option can be activated by clicking on the appropriate check-box in the Cleaning window. This
function allows for monitoring of the area in the flow chamber from which images are taken in order to check
the effectiveness of a cleaning routine. In the Previous area, an image of the previous state of the flow chamber
is displayed while the Current area on the right presents a live view of the flow chamber after a cleaning routine
has been carried out. The Live View should be turned off while a measurement or cleaning routine is being
carried out. If it has not been turned off, the Live View will be automatically stopped and the message, “warning:
live view has been stopped automatically”, will appear in the message area of the Cedex Control Center.
E
125
Automatic Adjustment
4
The automatic adjustment adjusts the focus position to ensure that images of consistent quality are taken
during measurements.
The service technician will carry out a focus adjustment before the initial operation of the Cedex Analyzer.
The focus adjustment is always necessary after the Analyzer has been moved. Additionally, Roche Diagnostics
recommends running a focus adjustment once per month for control purposes. Both the brightness and the
focus on the objects to be examined are optimally set during this focus adjustment. The focus adjustment lasts
approximately 20 minutes and is done with the Cedex Calibration Beads included in the contents of delivery.
If at all possible, the analyzer should never be turned off. If it is necessary to turn it off, the analyzer needs at
least 2 hours to warm up before an Automatic Adjustment can be carried out.
Proceed as follows to do the focus adjustment:
1
Open the Functions menu in the Control Center’s menu bar.
2
Click on Automatic adjustment to open the Automatic Adjustment and Alignment Verification window.
3
Pipette 1 ml of a well-mixed bead solution (Cedex Calibration Beads) into a Cedex Sample Cup.
4
Attach the Cedex Sample Cup to the sample port, or place the Cedex Sample Cup in the DefaultCup position
on the Multi Sample tray (see “The Multi Sampler DefaultCup”).
5
Click on the Start Automatic Adjustment button. You will be asked to verify that the beads have been
prepared. Click on OK to confirm and start the adjustment process.
■
E
126
Figure 77: The Automatic Focus Adjustment window after adjustment
The automatic adjustment is automatically carried out in several steps. First, water is pumped into the flow
chamber, after which the Cedex Calibration Beads are injected into the flow chamber.
The complete path of the microscope stage is scanned as it moves to its lowest and then to its highest position.
Based upon the obtained image information, a preliminary focus position is set. The area around the located
focus position is then examined closely and scanned several times to find the optimal focus.
An automatic cleaning of the flow chamber and the capillaries is done at the end of the adjustment. The focus
adjustment’s time-progression is displayed as an estimated value in the form of a blue progression bar.
The focus quality for every stage/focus position is displayed in a diagram. A distinct peak around the middle of
the graph indicates the optimal focus position.
The following criteria can be inspected to evaluate the result of an automatic focus adjustment:
Verify that the pink line marking the newly set focus lies within close range of the distinct peak.
E
New and previous focus position values are both displayed in the message box appearing at the end of the
focus adjustment. Ensure that variations between these values don’t exceed a range of +/-30.
The image quality should be checked. A valid image shows clearly outlined beads with a bright cell interior.
If any one or more of these criteria is not met, an authorized service technician must re-adjust the Cedex
Analyzer.
The Automatic Adjustment and Alignment Report can be printed out via the Print Report button.
127
Syringe Maintenance
Removing the Syringe
5
Syringe Maintenance
Moving parts of the Syringe Module may cause hand injuries. Never run a measurement on the
Cedex Analyzer without the protective cover for the Syringe Module in place. When performing a syringe
maintenance, be aware of the risks from moving parts.
The flow chamber, tubes, syringe and 8-way valve are cleaned during the Intensive Clean routine carried out by
the Liquid Management (see “Cleaning Options”).
However, the syringe is subject to wear and tear and must, therefore, be regularly replaced to maximize the life
span of the 8-way valve and to guarantee optimal performance. The syringe should be replaced approximately
every 6 months under normal use of the analyzer. More frequent use may require more frequent changing of
the syringe.
To change the syringe, follow the steps specified in the sections below:
5.1

The System Suitability Test (SST)
Creating SST Checkpoints
8
To ensure proper operation of the Cedex Analyzer and valid analysis results, it is essential that the system is
in good condition. The majority of the critical parameters are regulated by design or preventive maintenance
activities carried out by local Roche technical services. The routine check-ups performed by the user of the
Cedex Analyzer mainly focuses on the liquid management process (such as flow chamber, capillaries etc.).
A feature of the Cedex Software 2.2, the System Suitability Test (SST), is designed to help monitor the state of
the system for quality supervision/assurance purposes. A routine check-up procedure that meets the system
owner’s specific needs can be created using the SST software feature.
Verification that the Analyzer is in the required condition comprises both manual checks (internal as well
as external scrutiny of the equipment, e.g., chamber inspection) and various check-up and calibration
measurements. These individual procedures are known as SST checkpoints. When an SST is set up on a Cedex
System, checks and measurements will have to be performed on a regular basis. Passing the checkpoints will
then be mandatory for normal continuation of measurement procedures.
The System Suitability Test consists of different types of SST checkpoints. Each checkpoint needs to be created
and its parameters, including the acceptance criteria, configured by an authorized user (the Superuser or
Administrator). Once created and activated, the checkpoints apply to the whole system.
8.1
E
The System Suitability Test consists of different types of SST checkpoints. There are two main types of
checkpoints: an SST requiring inspection or maintenance activity performed by the user (e.g., syringe change,
chamber inspection) and SST procedures involving measurements with either Control Beads or Density
Reference Standard Beads. In order to pass a checkpoint involving Control Beads measurements, the average
result of a pre-defined number of one or more measurements needs to be valid according to the checkpoint
criteria. A checkpoint requiring an inspection or maintenance activity demands an active confirmation in the
System Suitability Test window that the activity or inspection has been performed.
Each checkpoint needs to be created and its parameters, including the acceptance criteria, configured by an
authorized user. For this, authorized users need to be assigned the SST edit function. Users who perform SST
procedures only need access to the SST run function. Once created and activated, the checkpoints apply to the
whole system.
On some systems, an inactive list of proposed SST checkpoints may be automatically provided in the System
Suitability Test List window. To activate these checkpoints, click in the box under the Active column for the
checkpoint. A check mark will appear in the Active column, which indicates that the checkpoint has been
activated.
132
8.1.1.
Creating SST Checkpoints With and Without Measurements
To create a new SST-Checkpoint, proceed as follows:
1
Click on SST in the Functions menu to access the System Suitability Test List window, or else click
directly on the SST button in the Control Center.
2
Click on the New button and the System Suitability Test New window will appear. Using this window, a
measurement checkpoint or a manual checkpoint can be created.
3
To create a checkpoint for a manual check or maintenance activity, click on the SST Without Measurement
button. This will open the System Suitability Test New window that allows for the creation of a checkpoint
for a manual check. Enter an SST Name (e.g., Flow Chamber) and an SST Description that provides sufficient
information for any user performing this SST.
4
To create checkpoints for calibration measurements, click on the SST including Measurement button. The
appropriate System Suitability Test New area will appear. A set of parameters needs to be defined. See
Table 2, for a detailed description of the parameters.
5
Click on the Save button to create a new SST checkpoint. The checkpoint will immediately be added to the
System Suitability Test List.
6
Clicking on Close will close the window without creating an SST checkpoint.
■
Parameters for SST including Measurement:
SST Name / SST Description
Enter an SST Name and Description for identification purposes during routine
check-up procedures.
Overall Type
Select the characteristic that is to be inspected during the measurements for this
checkpoint (e.g., Total Cell Count, Total Concentration) from the drop-down list.
Cell Type /Measurement
precision / Sample Volume /
Sample Initial Dilution
Define different measurement parameters for different checkpoints to verify
operational reliability in various situations.
Target Value
The Target Value serves as benchmark for the acceptance criteria. It can be
based, for example, on the average result of a set of measurements carried out
with Control Beads.
Offset
The offset in % determines the acceptance range applicable to the results of SST
measurements carried out for this checkpoint based on the target value entered.
Target Value Check /
Upper Limit / Lower Limit
If the Target Value Check is activated, the user carrying out SST measurements
can enter another target value before running the first SST measurement for this
checkpoint (e.g., when a new container of Control Beads is used). Acceptable
limits for what can be entered by a user for the variable target value are set using
Upper Limit and Lower Limit fields.
E
Note: the Upper Limit and Lower Limit fields are not related to the acceptable
range for results from an SST measurement! The acceptable range for results is
determined by the % entered in the Offset field.
Fixed Target Value
If the target value is not to be entered by users, the Fixed Target Value must be
activated.
Count For Passing
Count for Passing refers to the number of SST measurements that has to be
carried out for this checkpoint.
Table 2: SST parameters for SST with Measurement
133
In general, the Target Value is determined before the SST checkpoint is activated. For further information
on the procedure for the determination of a target value Roche technical services provides appropriate
recommendations. It is necessary to re-determine the target value if a new container of Control Beads is used.
An SST checkpoint includes a validity period. This can be set in the System Suitability Test List in the Days
Valid column. After this period of time, the SST procedures must be performed. If the SST procedure is not
performed within the validity period, all measurements apart from SST measurements will be prohibited (e.g.,
the system status is changed to MeasurementLock).
8.1.2.
Running a Water Blank
Before an SST including Measurement can be run, a water blank (Water For Injection [WFI]) should be run to
check the condition of the reagents. No more than 20 counts should be recorded for this measurement. This can
be scheduled using the SST including Measurement button (see “Creating SST checkpoints with and without
measurements”). The WFI measurement requires a relative deviation rather than an absolute deviation, which
means that 0 cannot be used as a Target Value as a relative deviation from 0 will always be 0.
Therefore, when setting up a WFI measurement, the Target Value should be set to 10 with a relative deviation
of 100%. This will result in an acceptance range of 0 – 20 objects (see Table 2).
8.1.3.
Setting up the SSTFailureReaction in the System Options Menu
The reaction of the system to an SST failure depends on the configuration in the System Options. The System
Options can be accessed under the Setup menu on the Control Center:
E
1
Open the System Options and click on the General tab.
2
Look for the parameter SSTFailureReaction.
Entering Restrict in the Value column will lead to prohibition of any further measurements, including SST
measurements, in the event of an SST failure. This will require a manual unlocking of the system in the
Lock – Unlock System area before measurement activity can be resumed (see “Locking – Unlocking the
System”).
If Warning is entered, measurement activity can be continued but there will be a warning about SST
failure before a measurement is carried out.
Choosing the Audit option will simply lead to a log entry in the audit trail file in the case of an SST failure.
There will not be any restrictions or warnings.
3
Click on Save to store the change.
■
Measurements that are run despite the fact that not all SST procedures are up to date or valid will have no
check-mark in the SST Valid box in the Measurement window.

Performing an SST
All procedures related to the System Suitability Test can be controlled via the System Suitability Test List. To
access the list, open the Functions menu in the Control Center and click on SST or directly click on the SST
button in the Control Center.
The System Suitability Test List provides an overview of all SST checkpoints and their current status. Valid SST
checkpoints are displayed in black while red indicates an invalid checkpoint. SST checkpoints need to be carried
out at regular intervals, the length of these intervals being specified in the Days Valid column. To confirm a
checkpoint, either manual checks have to be done or measurements need to be carried out.
It is recommended to include confirmation of checkpoints in the daily/weekly work routine and not to wait
until the validity period of a checkpoint has expired.
8.2.1.
Performing an SST with Measurements
If the SST to be performed requires a measurement or series of measurements, do the following:
1

field to the left of the appropriate line.
■
E
The Count For Passing value given in the System Suitability Test Measurement Run window indicates the
number of measurements that have to be carried out for this checkpoint. The average value will be calculated
from all of the measurements required for a particular SST checkpoint.
The average value of all test measurements needs to be within the acceptance range. The acceptance range is
defined by the target value and the offset (in %). In the event of an invalid SST measurement, the system will
immediately be locked. Once in SSTLock, the system needs to be unlocked manually by authorized users before
any further SST or other types of measurements can be carried out.
If the average result of all test measurements for an SST checkpoint is valid, the checkpoint will automatically
be displayed in black.

Locking – Unlocking the System
8.4
Measurements that are carried out after the validity period of an SST checkpoint has expired are marked as
invalid in the Audit Trail. In addition, the system may be locked for any further routine measurements except
SST measurements.
The System Status describes the capability of the system for performing certain tasks involving the hardware.
The current state of the system can be viewed in the Change System Status window, which is accessed by
selecting the Lock – Unlock System option in the System menu of the Control Center (see Figure 85).
The state of the system is set automatically depending on the validity of all SST checkpoints, and the
configuration of the SSTFailureReaction parameter in the System Options. Depending on the configuration,
if an SST checkpoint is out of date only SST measurements can be carried out. No routine measurements will
be possible (Current State: MeasurementLock). Once all SST checkpoints are up to date and valid again, the
system is fully usable and the Current State is automatically set to SystemOK.
In the event of a failed SST procedure, the system may be locked for any further measurements including
SST measurements (this is only the case if the SSTFailureReaction parameter in the System Options is set
on Restrict (see “Setting up the SSTFailureReaction in the System Options menu”). The Current State will be
automatically set to SSTLock.
The system status can be changed manually by authorized users. Manually changing the system status may be
necessary for a variety of reasons. For more details see the following table:

Trace and Logging
2
Trace and Logging
Trace and Logging are only required for support and problem detection purposes. Therefore, it is advisable
to restrict access to Trace and Logging to the support team and users with extended permissions (e.g., the
Superuser).
Trace and Logging functionality should only be activated at the request of an authorized service technician.
In order to avoid an exaggerated use of hard disk space, turn off the Trace and Logging functionalities as soon
as the issue has been located and/or resolved.
To activate or change Trace and Logging parameters, open the Setup menu in the Cedex Control Center.
Clicking on Trace & Logging will open the corresponding window.
The tracing functionality, as well as the logging functionality, can separately be enabled for individual modules
of the Cedex Analyzer.
Tracing is in the Off state by default. The application has two Trace Levels. The first one (tracing level Normal)
is used for minimal tracing required for time critical problems. The second level (tracing level Extended) is
necessary for a more detailed problem description. To set the Trace Level, click on the current status and a dropdown menu will appear from which level can be selected. Logging is in True state by default.
Trace and log records are saved in files which are accessible by using Windows Explorer. The records are found
in the C:\Cedex2 directory under CedexLog (CedexLogand_YYYY_MM_DD.log) and CedexTrace (CedexTrace_YYYY_MM_DD.log).
Target files for tracing and logging data can be defined in the System Options menu. These files will automatically
be created in the Cedex2 folder. The data will then be stored in the default target files as well as the newly defined
target files. Open the Tracing (Logging) tab and enter the desired target file path for the TraceOutputPath
(LogOutputPath) parameter in the Value column.

The System Audit Trail File
All user-initiated activities, as well as important actions carried out by the Cedex Software 2.2, are recorded
in the Audit Trail file. The system also logs all errors in the audit trail, including information from the error
message.
For each activity the User, Measurement ID, Workarea Name, Reactor Identifier and Sample Identifier are given.
The actions are classified by Event Types and a short message provides further explanation.
To support monitoring of user-initiated activities, a search filter is available that also allows for defining the
period of time which is to be searched.
A report can be printed by clicking on Print Report.

System Options und User Preferences
G
Appendix
1
The following list provides a description of all of the Systems Options that can be found in the Cedex Software
2.2 via the Systems Options window found under the Setup menu of the Cedex Control Center.
If an option exists in both the System Options window and the User Preferences window, the entries in the
User Preferences window take precedence over the entries found in the System Options. For example, if the
default Cell Type in the System Options window is “CT1”, but user “Joe” selected Cell Type “CT2” as the default
in the User Preferences window when he was logged in the default Cell Type will be “CT2” when the user “Joe”
is logged in. The defaults set in the System Options window will apply to new users who have not set their own
defaults in User Preferences window.
If the column SaveLastValue has been selected for a particular parameter (i.e., there is a cross in the column),
any new value entered in the corresponding location will be automatically saved in the System Options or the
User Preferences windows. For example, user “Joe” has set the default for the Cell Type in the Measurement
section of his User Preferences window to “CT1” and has activated the SaveLastValue option. If “Joe” changes
the Cell Type parameter to “CT2” when running a new measurement, “CT2” will be automatically saved as the
new default in his User Preferences window and will be automatically recommended for the next measurement.
The SaveLastValue function can be activated for all options in the System Options window and for all options
in the User Preferences window for every individual user.
If the system has been upgraded from some previous version to software version 2.2, it is possible that some
default settings in the System Options may have slightly different values than those described in this manual.
The settings described below apply to systems on which software version 2.2 has been installed as the original

Performing a Single Measurement — (May 2011)
Moving parts of the Multi Sampler may cause hand injuries. The Multi Sampler
needle may cause injuries during operation. Never use the Cedex Analyzer without the
protective cover in place for the Multi Sampler.
Start the Cedex Analyzer and Software
1
Switch on the Cedex Standard Analyzer.
2
Switch on the monitor and PC.
3
Log in to Windows XP.
4
Start the Cedex Software 2.2 by double clicking on the Cedex Client icon located on the
desktop (the Cedex Server should already be automatically started. It must be first started
before the Cedex Software 2.2 can be started). The Log In window of the Cedex Standard
Software 2.2 will open.
5
Enter the username in the User Name field and password in the Password field and press
<Return>. The Cedex Control Center appears after a successful login.
■
1
Click on the Measure button in the Cedex Control Center to open the Measurement
window.
2
In the Measurement window, enter a clearly defined Reactor ID to describe the sample
(e.g. the name of the cell culture or bioreactor name) in the Reactor ID area. You may either
choose a Reactor ID from the drop down list or enter a new Reactor ID.
3
Enter a clearly defined Sample ID in the Sample ID area. Multiple Sample IDs can be listed
under one Reactor ID. The Sample ID can be freely defined.
4
Choose the appropriate dilution factor from the Dilution drop-down list. For undiluted
samples, a dilution factor of 1:1 should be entered. When a dilution of 1:2 is prepared, then
1 part cell suspension has been added to 1 part dilution medium. A dilution of 1:3 means
that 1 part cell suspension has been added to 2 parts dilution medium. The dilution factor
will be automatically taken into account in the calculation of the results.
5
Select the sample volume of 1000 µL in the Volume drop-down menu.
6
Enter comments (if desired) in the Comment box.
7
Select the sample port type in the Sample Port drop-down list:
䉴 Auto Sampler: for systems with a Multi Sampler.
䉴
Perform a Hardware Startup and Prime
1
Click on the HWM button in the Cedex Control Center to open the Hardware Management
window. If the Hardware Management has not been started, the current status field will have
the message “Not started”.
2
Click on HW Startup if the Hardware Management has not been started. The Hardware
Management will start and the current status field will have the message “LM Shutdown”.
3
Ensure that a clean, empty Cedex Sample Cup is correctly positioned on the Multi Sample
Tray in the DefaultCup position (usually sample cup position 1) or on the single sample port
and click on Prime in the Hardware Management window.
Single: for systems with a single sample port.
8
Enter the cup position for the sample in the Cup Position window if there is a Multi Sampler.
9
Select the cell type that optimally recognizes your cells from the Cell Type drop-down list:
䉴 Factory-installed cell type is Std. Size (V5.00)
If a new cell type has been created, it can also be selected from the same Cell Type
drop-down list.

Select the desired precision level in the Precision drop-down list:
䉴 Minimum: 10 images are used for the analysis.
䉴
Normal: 20 images are used for the analysis.
䉴
Superior: 30 images are used for the analysis.
11
Prepare the sample. The Cedex Standard Analyzer requires a volume of 1000 µL +/- 10%.
Any greater variation in sample volume will lead to inaccurate results.
12
Attach the Cedex Sample Cup containing the sample to the sample port, or place it in the
appropriate sample cup position on the Multi Sample Tray. The sample cup is correctly
attached to the single sample port when it is in an upright position directly beneath it and
the capillary tube almost reaches the base of the sample cup.
13
Click on the Start Measurement button to start the measurement.
14
When the measurement is finished, the top section of the Result Data area in the
Measurement window will display the overall results from the measurement.
The bottom section displays, in succession, the results from each image taken.
1
Open the Hardware Management window (HWM button on the Control Center).
2
Click on LM Shutdown to shut down the Liquid Management system.
3
To log out of the Cedex Control Center, click on Logout under the System menu or on
the Logout button in the Cedex Control Center. The Cedex Software will be ended and
the login window will reappear.
4
Alternatively, shut down the Cedex Software by selecting Exit under the System menu or
by clicking on to close the Cedex Control Center window.
5
The security query, “Do you really want to exit the Cedex Control Center?“, will appear. Click
on Yes to shut down the program.
6
The sample cup from the last measurement should remain attached to the sample port during
the entire shutdown procedure and should only be removed when a new sample cup has
been attached for the next measurement. In the case of a Multi Sampler, a sample cup
should always be left in the DefaultCup position on the Multi Sample tray at all times
(see Quick Guide “Working with the Multi Sampler”).

Activate the status of each sample row by double clicking in the Status field of the row to
be activated. The row appears pale blue, and further modifications of sample information is
impossible. Return to the Edit status by double clicking on the Status area of the sample
row to allow for further changes, if desired.
7
Alternatively, activate or deactivate all samples simultaneously by double clicking on the
word Status in the column heading at the top of the Multi Run preparation area. Confirm
the safety query with Yes to accept the modification.

After some or all rows have been activated, click on the Start button on the right-hand side
of the Multi Run window to start the analysis of the activated measurements.
The position of the Cedex Sample Cup used for Prime, LM Shutdown, calibration and
cleaning routines is called the DefaultCup position. An empty Cedex Sample Cup must be
manually placed in the position set for the DefaultCup before running LM Shutdown, focus
adjustment, Prime and all cleaning routines. This Cedex Sample Cup does not differ from the
usual sample cups. The standard (default) position for the DefaultCup is position 1 of the
Multi Sample Tray.
Using the Multi Sample Tray
To insert the tray, gently push the tray into the notch until the automatic tray rope starts
pulling it in. To eject the tray, gently push on the tray. The tray will be automatically ejected.
The tray can only be ejected when the system is idle. It cannot be ejected if the system is
moving or the needle is down in a cup.

Modifying Data Entry, Changing Samples
Viewing results via the Multi Run Result List
Information about the operation and process parameters for samples that have not yet been
analyzed can be modified during the run as follows:
At the bottom of the Multi Run window, the Analyzed Measurements field displays the list of
results for measurements previously carried out. Measurements are listed in order of process
time, from the newest measurements at the top of the list to the oldest measurements at the
bottom. All measurements carried out using the Multi Run window will be displayed in this
field unless the Clear Resultlist button has been pressed, which will clear all measurement
results from the list.
1
Double-click on the Status field of the measurement to be modified. The status field will
indicate that the sample is in edit mode.
2
Make desired changes to the measurement.
3
Double-click on the Status field to re-activate the measurement
(status: active or scheduled).
In addition, measurements displayed in this field can be restricted to only the measurements
carried out by the user logged into the system (mine), measurements that have not yet been
printed out (unprinted), and/or measurements carried out on that particular day (today).
■
Other results, such as Average Diameter, can be added for display in the result list via the User
Preferences (see “Adjusting Result Display in the Measurement List and Multi Run windows”
in the Operator’s Guide). Double-click on a measurement to view all results. If the result
list has been cleared, previously carried out measurements can still be viewed, printed out
and exported via the Measurement List window (see “Using the Measurement List” in the
Operator’s Guide).

Sample rows in which data has not yet been entered can be filled out at any time while the
Multi Run is running. In addition, sample rows containing finished measurements (status:
done) can be cleared and prepared for a new measurement by double-clicking in the Status
field of the row with the finished measurement. Sample data for a measurement cannot be
modified after that measurement has begun.
