Overview

The CMS-6000 online gas chromatograph is used for monitoring the content of total hydrocarbons, methane, non methane total hydrocarbons, benzene, toluene, ethylbenzene, xylene, trimethylbenzene, styrene, isopropylbenzene, etc. in fixed pollution source exhaust gas. The entire process of the sample gas is at a high temperature of 180 ℃ without any cold spot heating. After quantitative analysis, valve injection, and chromatographic separation, it is detected by a dual hydrogen flame ionization detector (dual FID). The concentration of total hydrocarbons (THC) and methane (CH4) in the sample gas is determined by the pre FID, and the concentration of non methane total hydrocarbons (NMHC) is calculated by subtraction method, which is consistent with the national standard (HJ38-2017).
