  Non-methane total hydrocarbons (NMHC) refer to the sum of volatile hydrocarbons (mainly C2-C8) other than methane. It has been an important indicator of ambient air monitoring for a long time. GB16927-1996 stipulates that the factory boundary concentration standard of non-methane total hydrocarbons is 4 mg·m-3, "Determination of non-methane total hydrocarbons in stationary pollution source exhaust gas by gas chromatography".


Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses a gas chromatograph equipped with a double hydrogen flame detector and a double capillary column to analyze the total hydrocarbons, methane and oxygen peaks in the exhaust gas of fixed pollution sources to obtain the content of non-methane total hydrocarbons (NMHC). When When the chromatographic injection volume is 1.0 mL, the detection concentration of the method is 4×10-2mg/m3, and the quantitative detection concentration range of the method is 0.12¡«32 mg/m3. The preparation method and injection method of the unique standard gas are emphasized. , to ensure the accuracy of the non-methane total hydrocarbons (NMHC) test.
