浩瀚色谱（山东）应用技术开发有限公司,以双柱单氢火焰离子化检测器的气相色谱仪直接进行测定。进样1.0 mL样品分别进入汽化室的总烃柱和甲烷柱中,由于这两个柱子填充材料和长短差异,总烃先在FID上产生响应,然后甲烷在FID上产生响应。总烃的浓度扣除甲烷浓度和除烃空气氧的浓度值,即可得到非甲烷总烃(NMHC)的浓度,可以实现单次进样,同时完成总烃、甲烷、非甲烷总烃浓度的测定。用于环境空气和固定污染源有组织排放中NMHC含量分析,操作简单,实验结果满意。

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses a gas chromatograph with a dual column single hydrogen flame ionization detector for direct measurement. Inject 1.0 mL of the sample into the total hydrocarbon column and methane column of the vaporization chamber. Due to the difference in filling material and length between these two columns, the total hydrocarbon first responds on the FID, and then the methane responds on the FID. The concentration of non methane total hydrocarbons (NMHC) can be obtained by subtracting the concentration of methane and the concentration of oxygen in the dehydrogenated air from the concentration of total hydrocarbons. This allows for single injection and simultaneous determination of the concentrations of total hydrocarbons, methane, and non methane total hydrocarbons. Used for the analysis of NMHC content in organized emissions of ambient air and fixed pollution sources, with simple operation and satisfactory experimental results.
