传统的非甲烷总烃的测定，采用2根色谱柱，1根总烃柱，1根甲烷柱，分别测定总烃和甲烷，然后差减法，得出非甲烷总烃的含量。操作复杂，有时会出现负值，误差大。

　　浩瀚色谱研制1根填充柱，直接测定非甲烷总烃，无需2根色谱柱，分别测定总烃，甲烷，再差减法；定量准确，分析时间短，效率高，在赛默飞在线仪器上测试，效果满意。

　　The traditional method for determining non methane total hydrocarbons involves using 2 chromatography columns, 1 total hydrocarbon column, and 1 methane column, respectively, to determine total hydrocarbons and methane, and then subtracting to obtain the content of non methane total hydrocarbons. The operation is complex, and sometimes negative values may occur with large errors.

　　Haohan Chromatography developed one packed column for direct determination of non methane total hydrocarbons, without the need for two chromatography columns. Total hydrocarbons and methane were measured separately, and then subtracted; Accurate quantification, short analysis time, high efficiency, tested on Thermo Fisher online instruments with satisfactory results.
