System Components and Accessories for Sample Gas Conditioning
Data Sheet
10/235.20 EN January 2004
A gas analysis system usually consists of two groups of devices:
• The gas analyzer measures the concentrations of the sample
gas components and converts them into an electrical signal.
• Supplementary devices sample the sample gas from the
process, condition it and feed it in the gas analysis system.
Contents
In most cases, the sample gas sampled from the process cannot
be processed by the gas analyzer without further conditioning. Too
high a dust content, temperature and dew point as well as too high
or too low pressure, and not least interference components in the
sample gas can impair the operational capability of the gas analyzer and falsify the measuring result.
Supplementary devices such as the sampling probe, the sample
gas line, the sample gas cooler and pumps and filters ensure that
the sample gas inlet conditions of the connected gas analyzers are
satisfied and faultless measuring results are obtained independently of the process sequence and the local conditions.

Application and description
The tubular furnace is used to convert a non-measurable gas
component into a measurable compound which can be measured by a gas analyzer. This is for example necessary with
certain carbon, sulfur and halogen (such as chlorine) compounds. The conversion is performed in a reaction tube which
is filled with a catalyst and heated by the tubular furnace.
A further application of the tubular furnace is to remove interfering components without the other gas components being
affected.

Reaction Element
The reaction element with UV lamp is used for gases which
react chemically under the influence of UV light. A typical
application is the conversion of hydrogen (H2) with chlorine (Cl2)
into hydrochloric acid (HCl). For chlorine concentrations of less
than 85 Vol.-%, however, the tubular furnace CGO-9 should be
used in principle.
The sample gas is irradiated in a quartz reaction vessel by a
UV lamp. The lamp is mounted in the centre of the reaction
vessel so that the UV light radiates to all sides. This device is
housed in a plastic case. The formation of ozone outside the
reaction vessel is prevented by purging the case with nitrogen
or instrument air.

CGKW Condensate Monitor
Application
The condensate monitor CGKW is used to indicate moisture
(condensate) or any other electrically-conducting liquid which
penetrates into the sample gas line to the gas analyzer. At the
same time, the condensate monitor is a membrane filter and it
therefore satisfies the double function of fine filtering the sample gas as well as of signaling moisture. The filter membrane
holds back the penetrated concentrate for a short while. An
independent condensate barrier (see application examples)
can be constructed with the condensate monitor as sensor
element and the switching unit ER-144A/Ex (see page 36).
switching unit ER-144A/Ex, the apparatus is permitted in
hazardous areas of Zones 1 and 2 up to a gas and ambient
temperature of 55 °C without restriction of the explosion groups
and temperature classes.

ER-144A/Ex Switching Unit
The switching unit ER-144A/Ex acts as switching amplifier for
the condensate monitor CGKW (see page 35). The intrinsicallysafe circuit of the switching unit ER-144A/Ex enables the
condensate monitor also to be installed in hazardous areas.
The ER-144A/Ex switching unit operates in closed-circuit
operation. The alarm positions of the output contacts correspond to those of the device in a non-voltage state or exceeding the adjustable measurement current value (electric conductance) or disconnection of the sensor lead. In the “Ready”
status, the output contacts have changed over to the corresponding counter-position (internal relay picked-up).

A 100-kΩ resistor (1 % / 0.25 W) must be installed at the sensor
in order to monitor the signal line between the sensor and the
electrode relay. Without the resistor, the switching unit will
change to the “Line break” position.

Acid Filter
The acid filter is used in the gas conditioning system. Its purpose is to collect the sulfuric acid aerosols entrapped in the
sample gas. The acid filter may always be required where the
SO3 content in the sample gas is greater than 1 mg/m3 or the
SO2 content is greater than 1000 mg/m3 – for example in flue
gas from heavy-oil or hard coal firings.

Stripper for Cooling Water and Waste Water
The stripper enables traces of organic solvents or pollution in
waste water or cooling water to be monitored continuously.
The stripper is used in combination with a flame-ionization
detector (FID). The device operates on the flow principle.
100...300 l/h of the water to be analyzed are sent through a
glass body in the center of which is located a glass frit which is
continuously purged with the instrument air. Hydrocarbons
change into the gas phase and are driven out of the medium by
the air bubbles. The air stream is then analyzed with an FID.
The stripper unit is operated on the bypass principle without a
pump. The cross-sections of the entire unit are designed in
such a way that clogging is prevented to a greater or lesser
extent. A threefold safeguard against flooding and water breakthrough to the FID is achieved by an overflow and an
emergency overflow as well as a check valve. The feed can be
shut off by means of a gate valve. To obtain long-term
measurement stability, the strip air is fed via flow regulators.

Cylinder pressure reducers are used to reduce the filling
pressure in pure gas and test gas cylinders to the required
operating pressure. Material compatibility must be observed in
respect of the test gas (see technical data). Two-stage cylinder
pressure reducers are employed where very constant pressure
and flow are required at low operating pressure – for example
where the subsequent gas paths are switched over using
solenoid valves. Pressure reducers with minimum contact at
the high-pressure gauge give an indication when the cylinder
pressure has dropped to such a level that it is necessary to
replace the gas cylinder.
