Gas preparation

Sample gas and reference gas quality with own gas preparation
Note
Gas preparation
The analysis chamber may be contaminated if you do not prepare the gas sufficiently. This
can result in a measured value drift and temperature-dependent measuring errors.
● The sample gas/reference gas must be free of dust and condensation.
● Position the corresponding absorption filter before the device in order to filter out corrosive
components or components which interfere with measuring.
● Make sure that the sample gas does not condense in the gas preparation unit and in the
analyzer itself. Appropriate measures include heated sample gas lines, a heated analyzer,
or a compressor cooler.
● You can install the following devices upstream of the sample gas inlet for gas preparation:
– A gas sampling device
– A sample gas cooler
– A filter
– A gas suction pump
Depending on the composition of the sample gas, you may need additional equipment such
as a wash bottle, additional filters and pressure reducers.
Ensure that gas sampling devices, gas cooling devices, condensate vessels, filters and any
connected controllers, recorders or indicators are ready to operate (see the associated
operating instructions).
