传统的环境监测工作的实际情况,应用双柱双检测器气相色谱法,比较了非甲烷总烃不同的测定方法,探讨了在实际环境监测分析中非甲烷总烃测定过程的一些关键性技术问题,对色谱条件提出了几点优化建议,发现非甲烷总烃测定结果以甲烷计更接近实际监测情况,并验证了HJ/T 38—1999和HJ 604—2011方法中2种总烃标准曲线绘制方法的等效性,但在实际环境监测中HJ 604—2011方法操作更加简捷.双柱双检测器气相色谱法测定非甲烷总烃也存在严重的不足,基于FID响应值的非甲烷总烃不能准确反映空气有机污染程度,可能会掩盖空气中某些有机污染.

浩瀚色谱（山东）应用技术开发有限公司研发甲烷总烃复合柱HH-NMHC-1柱，一根色谱柱直接测定非甲烷总烃的含量，柱效高，分离好，操作简单，浩瀚色谱的产品。

应用：环境空气非甲烷总烃连续自动监测技术规定（试行）2021

In the actual situation of traditional environmental monitoring work, using double-column and double-detector gas chromatography, different determination methods of non-methane total hydrocarbons were compared, and some key technical problems in the determination process of non-methane total hydrocarbons in actual environmental monitoring and analysis were discussed. , some optimization suggestions for chromatographic conditions were put forward, and it was found that the measurement results of non-methane total hydrocarbons in terms of methane were closer to the actual monitoring situation, and the two standard curves of total hydrocarbons in the HJ/T 38-1999 and HJ 604-2011 methods were verified. The method is equivalent, but the HJ 604-2011 method is simpler to operate in actual environmental monitoring. The dual-column dual-detector gas chromatography method also has serious deficiencies in the determination of non-methane total hydrocarbons, and the non-methane total hydrocarbons based on the FID response value cannot be Accurately and comprehensively reflect the degree of organic pollution in the air, which may mask some organic pollution in the air.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. developed a methane total hydrocarbon composite column HH-NMHC-1 special column, a chromatographic column to directly measure the content of non-methane total hydrocarbons, high column efficiency, good separation, simple operation, Haohan chromatography Unique product.

Name: Methane total hydrocarbon composite column
