非甲烷總烴(NMHC)指除甲烷以外揮發(fā)性碳氫化合物(其中主要是C2—C8)的總合,長期以來一直是環(huán)境空氣監(jiān)測的一項重要指標(biāo),我國《大氣污染物綜合排放標(biāo)準》GB16927—1996規(guī)定非甲烷總烴的廠界濃度標(biāo)準為4 mg·m-3,《固定污染源排氣中非甲烷總烴的測定氣相色譜法》HJ/T 38—1999描述了具體的檢測方法

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
