The Science
 The science of testing a subject’s breath alcohol content is based on the principle
of Henry’s Law.
?
4 | 42
What is Henry’s Law?
Henry’s Law
 The English chemist Henry studied the
behavior of liquid solutions (mixtures)
containing one volatile component.
 In 1803, he set down his findings in
writing, known today as Henry’s Law.
 Although Henry did not work with alcohol
mixtures during his research, his findings
are also applicable to aqueous solutions
of alcohol containing less than 20
percent alcohol.
5 | 42
Henry’s Law
 The liquids water and alcohol
can be mixed in any ratio,
forming homogeneous mixtures.
Both liquids have a tendency to
evaporate from the liquid in the
form of gas. Alcohol has a
greater tendency to do this, and
its higher vapor pressure is also
evident from its smell, which can
be detected above the liquid.
6 | 42
Henry’s Law
 If an alcohol-water mixture of
this type is kept in a partly filled
and sealed bottle, the concentration of gaseous alcohol (and
water vapor) in the air above the
liquid will increase until a certain
concentration is reached.
 This concentration then
remains constant.
At this stage, there is a defined ratio between the
alcohol concentration in the liquid and that in the air.
7 | 42
Henry’s Law
The concentration of alcohol above the liquid alcohol-water mixture during the
vapor phase depends on just two factors:
1. The temperature of the mixture (solution)
and
2. The alcohol concentration in the liquid.
8 | 42
Henry’s Law
 If the air in the bottle is replaced
with air with a higher alcohol
concentration, alcohol will pass
from the air into the liquid until
the defined ratio between the
two concentrations (air and
liquid) is re-established,
provided the temperature
does not change.
 If the temperature of the liquid
rises, the alcohol concentration
in the air will likewise increase.
 The fixed ratio creates a
dynamic equilibrium.
9 | 42
Henry’s Law
This situation can be described as follows
“When an aqueous mixture of a volatile substance reaches equilibrium with air,
there will be a fixed ratio between the concentration of the substance in the air
and its concentration in the solution. This ratio remains constant for a given
temperature … ”
This ratio does not depend on the ambient pressure!
10 | 42
Henry’s Law
Henry’s Law also applies to the exchange processes in the human body,
especially in the lungs.
 The balance between alcohol in
the blood and in the breath is
created in the lungs in the same
way as described for alcohol in
aqueous solutions and air.
11 | 42
Henry’s Law
Henry’s Law states:
Applies to a person:
When an aqueous mixture of
blood
a volatile substance
alcohol
reaches equilibrium with air
in the lungs
there will be a
fixed ratio
Ratio: 2100:1
between the concentration of the substance in
the air and its concentration in the solution.
(concentration of alcohol in the blood to the
concentration of alcohol in the breath)
This ratio remains constant for a given
temperature.
body temperature is constant
The distribution of the volatile substance (alcohol) does not depend on the
ambient pressure, weight, and/or physique.

13 | 42
We have established how blood alcohol concentration can be measured
from breath, so what kind of technology do the Alcotest units use to measure
the concentration of breath alcohol?
Fuel Cells
The Alcotest® 6810 and 6820 use an
electrochemical fuel cell to measure
alcohol in breath. The fuel cell consists of a
porous, acidic membrane (electrolyte) which
is laminated by two platinum black plates. An
electric wire is attached to each plate. This
assembly has a gas inlet leading into a
sample chamber.
If ethanol reaches the plate, a chemical
reaction is triggered producing an electrical
current between the two plates. The amount
of ethanol consumed by the fuel cell is
proportional to the ethanol concentration in
the breath sample. The current is measured
and shows us the ethanol concentration in the
breath sample, and thus, the concentration in
the blood.
14 | 42
Feed the fuel cell: Not using the device
will not extend the lifespan of the fuel cell.
The fuel cell will last longer if used regularly
and if regular accuracy checks are
performed.
Fuel Cells
Principle:
Platinum
electrode
 The alcohol is oxidized electrochemically on a selective,
catalytic platinum electrode
 This generates an electrode
current (electric current) or
voltage
 The higher the alcohol content of
a sample of known volume, the
higher the resulting voltage or
total current
15 | 42
Alcohol
Electric
current
Current measurement does not produce
a continuous signal. Instead, the current
rises at first and then falls when the sample
is processed.

Both batteries should be inserted according to
polarity markings (positive end up).
Note: If the device will be stored for a long period of time, remove the
batteries to prevent corrosion.
20 | 42
Attaching the Mouthpiece
Open the packaging. To maintain hygienic conditions, keep the portions of the mouthpiece that will
come in contact with the subject’s mouth covered by the packaging until the mouthpiece is attached
to the instrument.
Slide the mouthpiece up at a 45° angle along the edge of the mouthpiece channel until the ejection
tab comes into contact with the edge of the device. Push down on the top of the mouthpiece in the
grooved section until the mouthpiece clicks into place. With practice, the mouthpiece can be
attached without visual observation.
21 | 42
Conditions for Testing
Make sure the following conditions are met when performing a breath test.
These conditions ensure the test is accurate:
 Use a new mouthpiece for each subject.
 Do not unnecessarily introduce unrealistically high mouth alcohol concentrations
as this reduces the life of the fuel cell.
 Do not test the subject within 15 minutes of their drinking any alcoholic beverages
or putting any alcoholic substance in their mouth. Observe the 15 minute
deprivation period.
 Ensure the subject breathes normally before giving the breath sample.
 The device will ensure the minimum sample volume and blow
time requirements are met for a valid sample.
15 min

Powering on the Device
 To turn the device on, press and hold the
green “OK” button.
 Likewise, to turn off the device, press and
hold the green “OK” button until the device
shuts off.
23 | 42
Performing a Breath Test
1. Hold the instrument in front of the
subject and instruct the subject to
take a deep breath blow into the
instrument in one continuous
breath. The display will indicate
“BLOW” and a tone will sound to
show the breath sample is being
given correctly.
2. When the tone stops the breath
sample has been collected and the
results will display on the screen
within a few seconds.
3. Press the “OK” button when done
viewing the results to return to the
Ready screen.
24 | 42
Memory Storage
 Data memory for download of up to 5,000 tests with test
number, date/time, reason code, etc.
 Over 200 of the most recent tests can be recalled and
reprinted at any time. These are overwritten in a first-in,
first-out sequence.
 Download of stored data via PC-program diagnostics
(Windows 7 optimized).

25 | 42
Printer
 Dräger mobile printer
(magnetic)
 An optical interface
(LED above the display on
the Alcotest 6820)
enables wireless
transmission of data to
the mobile printer onsite.
LED light must be lit before
transmitting information to
the printer.
Printout of test results
26 | 42
Printing
Mobile printer
Using the printer:
 Press the green button to turn the printer on
 Press and hold the green button to turn the
printer off
The printer will slowly blink a green light to
indicate that the printer is on. Note that the
printer will automatically shut itself off after
two minutes with no activity.
27 | 42
Printing
Printing with the mobile printer
 When a test is completed on the 6820, the result
is displayed. To print the results, align the optical
light above the display on the 6820 with the
optical port on the printer located immediately
to the right of the green button. When they are
aligned the printer will print the test results, as
long as the green light on the 6820 flickers or is
lit.
 You can also go into the “last tests” menu of the
6820 and recall the previous result (more than
200 of the most recent tests are available in this
function). While the result is displayed, align the
optical ports in the same way and the printer will
print the result of the test.
28 | 42
Test Troubleshooting
 If you get an “Insufficient Volume” error
message instruct the subject to blow longer
or harder as needed.
 If you get a “Blow Interruption” error message
then the subject inhaled or abruptly stopped
blowing. Instruct the subject to extend out the
exhaling if they are blowing in a short puff.
 If the subject is having trouble blowing long
enough for the test due to a medical condition,
consider collecting a manual sample.
29 | 42
Sampling Mode
The 6810 and 6820 also allow for two other
sampling modes:
 Passive
 Manual
30 | 42
Passive Sampling
 Passive sampling can be performed by removing the
mouthpiece. With no attachment, quickly press and
release the “OK” button to sample the air. If alcohol
was present in the sample “Alcohol” will be displayed.
Likewise, if no alcohol was present, a “No Alcohol”
result will be displayed.
 While an attachment is not necessary for passive
sampling, a passive sample cone is available.
31 | 42
Manual Sampling
 If a subject is unable to provide a sufficient sample due to a medical/health
condition, a manual sample can be taken. While the subject is blowing,
quickly press and release the OK button. A sample will be drawn at this time.
 Note: This mode should not be used as a standard because the sample at
the end of breath is more indicative of the alcohol concentration in the blood.
?
32 | 42
The result will be displayed and stored with “MAN” (indicating this was a
manual sample).
Mouthpiece Disposal
 After performing a breath
test, detach the mouthpiece
by pushing up on the ejection
tab until the mouthpiece
clicks out of the mouthpiece
receptacle. Dispose of the
mouthpiece in accordance
with local regulations.
33 | 42
Diagnostics
Diagnostics software
 The 6810 and 6820 can be
connected to a PC with the
USB cable. The installed
diagnostics software
provides access to stored
results for reference or
retrieval.
 The USB cable (sold
separately) is necessary
to download data from
the device.

Accuracy Check
An accuracy verification or accuracy check is important for verifying accuracy of the
device and should be performed according to local rules and regulations. We also
recommend it be done after every calibration to verify the instrument’s accuracy.
There are two ways to perform an accuracy check: With a NIST traceable dry gas
standard or a wet-bath simulator.
36 | 42
Dry gas requirements
Dry gas should meet the following standards:
 Manufacturer and product must be on
NHTSAs CPL list.
 Concentration must match the set point
selected in the 6810 or 6820.
 Dry gas must not be past its expiration date.
 Do not transport dry gas by plane.
 If you wish to ship dry gas make sure to get
the proper hazmat certifications.
37 | 42
 Dry gas is prepared so that the desired
alcohol concentration is obtained at normal
atmospheric pressure. However,
atmospheric pressure varies slightly from
day to day by location. The most significant
change comes from elevation. In order to
compensate for these changes, the
Alcotest® 6810 and 6820 will automatically
adjust the measurement results based on
the elevation entered by applying the
altitude correct factor.
Performing a dry gas accuracy check
To perform a dry gas accuracy check:
 Regulator should be between 6 and 14 LPM.
 Attach the regulator to the dry gas canister.
 Place a rubber mouthpiece adapter on a standard
mouthpiece and push the adapter onto the
regulator nozzle.
 Slide and click the mouthpiece onto the device.
 Turn the device on and push the menu button
to access the quick menu.
 Select “Accuracy Check” and confirm the
information listed regarding gas type and
concentration by selecting “Next”.
 When the device shows “Supply Gas” push the
button on the regulator and a tone will sound. Hold
it down until the tone stops.
 Afterwards the results are displayed on the screen.
38 | 42
Performing a wet bath accuracy check
To perform a wet bath accuracy check:
 Turn on the simulator, leak check it, and give it time to heat
for the check.
 Place a rubber mouthpiece adapter on a standard
mouthpiece and push the adapter onto the metal nozzle.
 Slide the mouthpiece onto the device.
 Turn the device on and push the menu button to access the
quick menu.
 Select “Accuracy Check” and confirm the information listed
regarding gas type and concentration by selecting “Next”.
 When the device shows “Supply Gas” push put a simulator
mouthpiece on the simulator hose and blow. A tone will
sound. Blow until the tone stops.
 Afterwards the results are displayed.
