Description

Technical Field

[0001] The technical field related to the present utility model, in particular to a multifunctional gas conversion device. Background Art

[0002] At present, hydrogen flame ionization detector and flame photometric detector are two different types of detectors for gas chromatograph. When they work, they need to provide combustion-supporting gas. If the combustion-supporting gas contains hydrocarbon components, the instrument noise is relatively large, thus reducing the sensitivity. Therefore, a hydrocarbon removal module is required to remove the hydrocarbon components in the combustion-supporting gas. On the other hand, if the combustion-supporting gas contains water and dust components, it will affect the detector. In addition, when analyzing trace carbon monoxide and carbon dioxide in gas samples by hydrogen flame ionization detector, it needs to be catalytically converted by a methane conversion module.

[0003] Most of the existing hydrocarbon removal modules, filtration modules and methane conversion modules are independent. When multiple hydrocarbon removal, filtration and methane conversion modules are configured in a gas chromatograph, the volume is relatively large, occupying a large amount of column oven space. And each independent module needs to be separately temperature-measured and heated, which is not easy to maintain. Therefore, it is of great significance to develop a multifunctional gas conversion device. Summary of the Utility Model
