Catalytic purification filter

Filter is used for:

1. Carrier-gas purification from excess content of oxygen. Filter is used for purification of nitrogen and helium from oxygen, for example, during work with electronic capture detector (ECD), thermal conductivity detector (TCD) or during work on capillary columns (to avoid malfunction of column or to increase sensitivity of detector). Filter can be used for purification from oxygen and other gases (including argon and hydrogen). Regeneration of catalyst in the filter is done via hydrogen purging. Work of the filter is fully automated.
2. Air purification from organic impurities. Filter is used for purification of air from organic impurities, for example, during work with flame detectors and when using air as carrier-gas. Filter can be used for purification from hydrocarbon impurities and other gases, for example, purification of nitrogen from hydrocarbons. Regeneration of the filter catalyst is done via pure air purging. Work of the filter is fully automated.

Catalytic purification gas filter is designed for catalytic purification of gas flows that feed gas chromatographs. Gases that feed gas chromatographs are: nitrogen, argon, hydrogen, helium and also air, that can be either carrier-gas or optional gas for feeding of flame detectors.
