“非甲烷總烴”的定義是：除甲烷以外所有碳?xì)浠衔锏目偡Q，主要包括烷烴、烯烴、芳香烴和含氧烴等組分。

非甲烷總烴的測(cè)定方法為氣相色譜法，利用差減法測(cè)定非甲烷總烴的含量；具體的，定量體積樣品氣通過(guò)氣相色譜柱分離甲烷，經(jīng)fid測(cè)量甲烷含量，同等體積樣品氣體，不經(jīng)分離甲烷，通入同一fid測(cè)量總烴含量，將總烴含量減去甲烷含量即得到非甲烷總烴的含量。

"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.
