《HJ 604-2017环境空气 总烃、甲烷和非甲烷总烃的测定 直接进样-气相色谱法》
差减法，采用10通加6通阀双阀、双定量环、双色谱柱、单fid或双fid的方式分别实现总烃、甲烷的测量，最后非甲烷总烃的测量结果为：非甲烷总烃＝总烃-甲烷。

名称：PQ甲烷柱
规格：2m*1/8
*高温度：250°C
编号：20230901111
应用：环境空气，固定污染源废气中甲烷，总烃，非甲烷总烃的测定 气相色谱法
HJ 604-2017 Determination of total hydrocarbons, methane, and non methane total hydrocarbons in ambient air - Direct injection gas chromatography method
The difference method uses a 10 way plus 6 way valve dual valve, dual quantitative ring, dual chromatographic column, single fid or dual fid method to achieve the measurement of total hydrocarbons and methane, respectively. The final measurement result of non methane total hydrocarbons is: non methane total hydrocarbons=total hydrocarbons methane.
Chromatographic column: Porapak Q 1/8 " × 2m
Name: PQ Methane Column
Specification: 2m * 1/8
*High temperature: 250 ° C
No.: 20230901111
Application: Determination of methane, total hydrocarbons, and non methane total hydrocarbons in ambient air and fixed source exhaust gas Gas chromatography method
