SP-3420A Detailed information of dedicated gas chromatograph for detecting total hydrocarbons and non methane total hydrocarbons in the air:
1、 Overview of detection methods for total hydrocarbons and non methane total hydrocarbons in the air
Non methane total hydrocarbons (NMHC) typically refer to all volatile hydrocarbons other than methane, also known as non methane total hydrocarbons. When the concentration of NMHC in the atmosphere exceeds a certain level, it is harmful to human health and can also produce chemical smoke, causing harm to the environment and humans. The factory boundary concentration standard for non methane total hydrocarbons in China's "Comprehensive Emission Standards for Air Pollutants" (GB16927-1996) is 5mg/m3

The gas chromatograph for detecting total hydrocarbons and non methane total hydrocarbons in the air adopts a single FID detection process with a ten way valve for one-time injection and dual column parallel connection, effectively eliminating measurement errors caused by differences in FID sensitivity during dual FID analysis, meeting the detection requirements for total hydrocarbons and non methane total hydrocarbons in the air, with a minimum detection concentration of 0.05mg/m3; And only one injection is needed to analyze both total hydrocarbons and non methane total hydrocarbons simultaneously
The GC-7860E gas chromatograph for the detection of total hydrocarbons and non methane total hydrocarbons in the air meets the requirements of analytical methods such as GB/T15263-94 "Determination of total hydrocarbons in ambient air by gas chromatography", HJ/T38-1999 "Determination of non methane total hydrocarbons in fixed source exhaust gas by gas chromatography", and "Air and exhaust gas monitoring methods (Fourth edition)".
