Intended for gas cleaning from oxygen and organic impurities by heating in the presence of catalyst.
Catalytic filter is commonly used to nitrogen cleaning from oxygen when working with ECD as well as with WAX or FFAP column types, and also to compressed air cleaning from organic impurities when supplying flames detectors or when air is used as carrier gas. Oxygen absorptions channel can be recovered with hydrogen flow:
Three modifications of filters are available:
1. Filter 20.0-01 - air cleaning from organics (up to 0.1mg/m3 and less)
2. Filter 20.0-02- carrier gas cleaning from oxygen (up to 5 ppmv and less)
3. Filter 20.0-03 – dual channel filter, combining -01 and 02 models
