甲烷柱非甲烷总烃测定 详细信息：

名称：甲烷柱
规格：3m*1/8
型号：GDX-502
应用：环境空气/固定污染源废气总烃/甲烷/非甲烷总烃测定 气相色谱法

此柱分离好，柱效高，O2与甲烷完全分离，不干扰

滕州市浩瀚色谱仪器技术服务有限公司，与环境监测工作的现实状况相结合,利用双柱双检测器气相色谱对某地非甲烷总烃含量进行测定,并除去了空气中氧含量对非甲烷总烃数值的影响。对非甲烷总烃类测定中存在的一些问题以及利用双柱双检测器气相色谱法测定非甲烷总烃存在的不足之处进行分析。结果表明,FID的响应值无法精准的体现空气中非甲烷总烃污染程度。

Methane column non-methane total hydrocarbon determination
Determination of non-methane total hydrocarbons in methane column Details:

Name: Methane Column
Specification: 3m*1/8
Model: GDX-502
Application: Determination of ambient air/stationary pollution source exhaust gas total hydrocarbon/methane/non-methane total hydrocarbon gas chromatography

This column has good separation and high column efficiency. O2 and methane are completely separated without interference

Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd., combined with the actual situation of environmental monitoring work, uses dual-column dual-detector gas chromatography to determine the content of non-methane total hydrocarbons in a certain place, and removes the oxygen content in the air and the total non-methane content. Influence of hydrocarbon value. Some problems in the determination of total non-methane hydrocarbons and the shortcomings of the determination of total non-methane hydrocarbons by dual-column dual-detector gas chromatography are analyzed. The results show that the response value of FID cannot accurately reflect the pollution degree of non-methane total hydrocarbons in the air.
