Function and layout of the multi X 2500 multi X 2500

The argon safety bypass (2 in Fig. 16) prevents that the desiccant (sulfuric acid) is
drawn into the gas transfer line by a vacuum while the gas supply is turned on. A
vacuum may build up when the device cools down.
A replaceable filter has been integrated in the auto-protection assembly. The filter
protects the downstream assemblies (drying units, detectors) in case of an incomplete
combustion of carbon particles. The filter also retains condensed water and other
aerosols. Only water vapor can pass through the filter.
3.5 Chlorine module multi X 2500
The chlorine module (Cl module) consists of the following main components:

Wide-range coulometer for amperometric and potentiometric titration

Stirrer/cooling block for the measuring cell (with automatic cell detection)

Measuring cell with electrodes with gas inlet tube

Intake pump

Adsorption tube

Sulfuric acid container for the operation with multi-purpose combustion tube
In the standard version, the intake pump draws the measuring gas from the
multi X 2500 directly into the measuring cell of the chlorine module when working
with an open combustion tube. The adsorption tube is introduced between the gas
outlet of the measuring cell and the intake pump. The adsorption tube protects the
intake pump against acetic acid vapors. Active carbon is used as adsorption agent.
In the chlorine module, the sulfuric acid container is only used when working with the
optional multi-purpose combustion tube.
All components of the module which are operated or serviced by the user can be
reached via the front door.
