在永jiu气体氢气，O2，N2，CO,CH4,CO2的分析过程中，通常使用5A填充柱，然而5A填充柱容易受到水及二氧化碳的毒化，从而降低分离度，柱效下降快，使用寿命短。

浩瀚色谱（山东）应用技术开发有限公司系统研究了气相色谱法测定焦炉煤气中组分方法，选用高纯氩气做载气，以复合5A色谱柱分离煤气中H2、O2、N2、CO和CH4，以GDX-502色谱柱分离 C2H4、C2H6和C3H8。以上组分用热导检测器和氢火焰离子化检测器进行检测。

此柱柱效高，分离好，zui大限度的克服了微量水分及二氧化碳的影响，效果良好。

In the analysis process of permanent gas hydrogen, O2, N2, CO, CH4, CO2, 5A packed column is usually used, but 5A packed column is susceptible to water and carbon dioxide poisoning, which reduces the resolution, the efficiency of the column drops quickly, and the service life short.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has systematically studied the method of gas chromatography for the determination of components in coke oven gas, using high-purity argon as the carrier gas, and separating H2, O2, N2, CO, and CO in the gas with a composite 5A chromatographic column. For CH4, C2H4, C2H6 and C3H8 were separated by GDX-502 chromatographic column. The above components are detected with a thermal conductivity detector and a hydrogen flame ionization detector.

This column has high column efficiency and good separation. It can overcome the influence of trace moisture and carbon dioxide to the greatest extent, and the effect is good.
