Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. uses a gas chromatograph flame ionization detector to determine the content of total hydrocarbons and methane in the air. The difference between the two is the content of non-methane total hydrocarbons. There are many reasons for the high analysis results of non-methane total hydrocarbons, mainly from the analysis of the standard curve concentration, sampling vessel, storage time, etc., to find out the main reasons for the impact to ensure that the content of non-methane total hydrocarbons in the ambient atmosphere is true and accurate .
