Non methane total hydrocarbon (NMHC) refers to the sum of volatile hydrocarbons (mainly C2-C8) other than methane, and has long been an important indicator for ambient air monitoring. China's Comprehensive Emission Standard for Air Pollutants (GB16927-1996) stipulates that the boundary concentration standard for NMHC is 4 mg · m-3. The specific detection method is described in the "Determination of Non methane Total Hydrocarbons in Exhaust Gas from Stationary Pollution Sources by Gas Chromatography" HJ/T 38-1999
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has achieved rapid and accurate determination of non methane total hydrocarbons in ambient air and waste gas from pollution sources through the use of a dual valve and dual column gas phase system
