3.2.1 Gas Conditioning
All gases must be supplied to the analyzer as conditioned gases! When the system is
used with corrosive gases, it must be verified that there are no gas components which
may damage the gas path components.
The gas conditioning must meet the following conditions:
Free of condensable constituents
Free of dust above 2 µm
Free of aggressive constituents which may damage the gas paths
Temperature and pressure in accordance with the specifications
When analyzing vapors, the dewpoint of the sample gas must be at least 10 °C below
the ambient temperature in order to avoid the precipitation of condensate in the gas
paths.
An optional barometric pressure compensation feature can be supplied for the µCEM.
This requires a pressure sensor with a range of 800 – 1,100 hPa. The concentration
