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。
浩瀚色谱（山东）应用技术开发有限公司依据HJ 604-2017对环境空气中总烃,甲烷和非甲烷总烃进行测定,使用GC-790型色谱分析仪,选择了合适的色谱操作参数,标准气体校正了分析仪,将空气样品直接进样分析.实验结果表明,应用气相色谱法测定环境空气中总烃,甲烷和非甲烷总烃含量,方法简便快速,线性关系良好,具有可靠的准确度和精密度.

Non-methane total hydrocarbons (NMHC) refer to the sum of volatile hydrocarbons (mainly C2-C8) other than methane, which have long been an important indicator of ambient air monitoring. GB16927-1996 stipulates that the factory boundary concentration standard of non-methane total hydrocarbons is 4 mg·m-3, and "Gas Chromatography Method for Determination of Non-methane Total Hydrocarbons in Exhaust Gas from Stationary Pollution Sources" HJ/T 38-1999 describes the specific detection method.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. determined the total hydrocarbons, methane and non-methane total hydrocarbons in ambient air according to HJ 604-2017, using a GC-790 chromatographic analyzer, selected appropriate chromatographic operating parameters, standard gas The analyzer was calibrated and the air sample was directly injected for analysis. The experimental results showed that the gas chromatography was used to determine the total hydrocarbons, methane and non-methane total hydrocarbons in ambient air. The method is simple, fast, has a good linear relationship, and has reliable accuracy and precision.
