非甲烷总烃(NMHC)指除甲烷以外挥发性碳氢化合物(其中主要是C2—C8)的总合,长期以来一直是环境空气监测的一项重要指标,我国《大气污染物综合排放标准》GB16927—1996规定非甲烷总烃的厂界浓度标准为4 mg·m-3,《固定污染源排气中非甲烷总烃的测定气相色谱法》HJ/T 38—1999描述了具体的检测方法

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
