Analysis of trace impurities in propylene

The GC-9560-GAS propylene trace impurity chromatograph is suitable for detecting trace impurities in industrial ethylene and propylene gases. It can complete the analysis of hydrogen, oxygen, carbon monoxide, carbon dioxide, acetylene, and methanol in ethylene and propylene with one injection. The instrument is equipped with VICI's highly sensitive helium ionization (PDHID) detector; Adopting the central cutting and blowback technology with four valves and five columns of Huaai chromatography, the injection valve adopts a six way or ten way valve with blowback protection gas path, together with helium purifier, non dead volume sampling valve and other components to form a complete gas analysis solution.
