“非甲烷总烃”的定义是：除甲烷以外所有碳氢化合物的总称，主要包括烷烃、烯烃、芳香烃和含氧烃等组分。
非甲烷总烃的测定方法为气相色谱法，利用差减法测定非甲烷总烃的含量；具体的，定量体积样品气通过气相色谱柱分离甲烷，经fid测量甲烷含量，同等体积样品气体，不经分离甲烷，通入同一fid测量总烃含量，将总烃含量减去甲烷含量即得到非甲烷总烃的含量。

"Non methane total hydrocarbon" is defined as the general term of all hydrocarbons except methane, mainly including alkanes, olefins, Aromatic hydrocarbon, oxygenated hydrocarbons and other components.
The determination method for non methane total hydrocarbons is gas chromatography, which uses the subtraction method to determine the content of non methane total hydrocarbons; Specifically, a quantitative volume of sample gas is separated from methane through a gas chromatography column, and the methane content is measured through a FID. For the same volume of sample gas, without separating methane, the total hydrocarbon content is measured through the same FID. The total hydrocarbon content is subtracted from the methane content to obtain the non methane total hydrocarbon content.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a direct measurement of non methane total hydrocarbons using one chromatographic column with high column efficiency, good separation, and satisfactory results.
