非甲烷总烃（NMHC）是除甲烷以外所有碳氢化合物的总和，具有较高光化学活性，是大气污染防控的重要对象。其来源广泛，包括工业排放、汽车尾气等，可通过气相色谱法等方法检测，需通过废气治理、清洁能源推广等手段控制。
浩瀚色谱（山东）应用技术开发有限公司，建立一种气相色谱法配双柱双氢火焰离子化检测器（FID）同时测定环境空气中的总烃和非甲烷总烃含量的方法。采样点位采集的样品中的总烃、甲烷含量进行了测定,计算出的非甲烷总烃质量浓度都小于1.0mg·m-3,以这两个样品为基质进行加标回收试验,总烃和甲烷的回收率分别为103%～106%,108%～110%;测定值的相对标准偏差（n=5）分别为1.18%～1.79%,1.99%～2.05%。

Non methane total hydrocarbons (NMHC) are the sum of all hydrocarbons except methane, with high photocatalytic activity, and are important targets for air pollution prevention and control. It has a wide range of sources, including industrial emissions, automobile exhaust, etc. It can be detected by gas chromatography and other methods, and needs to be controlled through waste gas treatment, clean energy promotion, and other means.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a method for simultaneous determination of total hydrocarbons and non methane total hydrocarbons in ambient air using gas chromatography with a dual column dual hydrogen flame ionization detector (FID). The total hydrocarbon and methane content in the samples collected at the sampling point were determined, and the calculated mass concentration of non methane total hydrocarbons was less than 1.0mg · m-3. Using these two samples as matrices for spiked recovery experiments, the recovery rates of total hydrocarbons and methane were 103% to 106% and 108% to 110%, respectively; The relative standard deviations (n=5) of the measured values are 1.18% to 1.79% and 1.99% to 2.05%, respectively.
