Description

Odor Gas Analyzer is a kind of gas analysis product developed for online analysis of odor gases in fugitive emission source and ambient air. Based on Ultraviolet Differentia Optical Absorption Spectroscopy and PLS algorithm, the analyzer can monitor multiple odor gases in the air, including methyl mercaptan, dimethyl sulfide, methyl disulfide, styrene, carbon disulfide, sulfuretted hydrogen, ammonia, trimethylamine, TVOCs, OU value, etc. In addition, it can be extended to monitor other components like SO, NO, CO, etc. Features It can directly monitor the concentration value of each component of odorous gas with fast response speed. It uses high-resolution spectrometer with low detection limit. The PLS algorithm can effectively eliminate the cross-interference between components. It uses long-life pulsed xenon light source, and the whole machine has no optical moving parts. The instrument has high stability. The system has built-in constant temperature components, small temperature drift, and strong environmental adaptability.
