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 hydrocarbons (NMHC) refer to the sum of volatile hydrocarbons (mainly C2-C8) other than methane, and have long been an important indicator for environmental air monitoring. China's "Comprehensive Emission Standard for Air Pollutants" GB16927-1996 stipulates a boundary concentration standard of 4 mg · m-3 for non methane total hydrocarbons. The "Determination of Non methane Total Hydrocarbons in Exhaust Gas from Fixed Pollution Sources by Gas Chromatography" HJ/T 38-1999 describes specific detection methods

　　Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has achieved rapid and accurate determination of non methane total hydrocarbons in environmental air and pollution source exhaust gas using a dual valve and dual column gas phase system
