滕州市浩瀚色谱仪器技术服务有限公司，，结合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全面反映空气有机污染程度,可能会掩盖空气中某些有机污染。

5-meter packed column for determination of total non-methane hydrocarbons
5-meter packed column for determination of non-methane total hydrocarbons Details:

Name: Total Hydrocarbon Column
Specification: 5m*3mm
Model: HH-Empty column5
Application: Non-methane total hydrocarbon analysis, high column efficiency, no bifurcation, good separation, and satisfactory results.

Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. keeps pace with the times, combines the actual situation of environmental monitoring work, applies dual-column dual-detector gas chromatography, compares different determination methods of non-methane total hydrocarbons, and explores the actual environmental monitoring In the analysis of some key technical issues in the determination of non-methane total hydrocarbons, several optimization suggestions were put forward for the chromatographic conditions. It was found that the measurement results of non-methane total hydrocarbons in terms of methane were closer to the actual monitoring situation, and verified HJ/T 38-1999 It is equivalent to the two total hydrocarbon standard curve drawing methods in the HJ 604-2011 method, but the HJ 604-2011 method is more simple and convenient in actual environmental monitoring. The dual-column dual-detector gas chromatography method for the determination of non-methane total hydrocarbons also has serious shortcomings. The non-methane total hydrocarbons based on the FID response value cannot accurately and comprehensively reflect the degree of air organic pollution, and may cover some organic pollution in the air.
