岛津MS-13X填充柱 人工煤气成份气相色谱分析

名称：填充柱

规格：3m*1/8

型号：MS-13X

应用： 煤气全分析中的应用 O2,N2,CH4,CO测定

目前国内外在使用气相色谱仪对人工煤气成份进行分析时,大多采用多台机、组合柱来完成。我国城市燃气中人工煤气成份气相色谱分析方法国家标准规定分析氢、氧、氮、一氧化碳、二氧化碳、甲烷、乙烯、乙烷、丙烯和丙烷等10个主要成份。

到目前为止国内外在煤气的色谱分析中,几乎全部采用5A(或13X)分子筛作为固定相。其缺点是遇水则分离效率迅速下降,在常温下对CO_2和几乎所有的有机化合物产生性吸附而中毒。因此这种固定相在使用时其性能一直处于变化过程之中,给定量工作带来了很多困难。

浩瀚色谱（山东）应用技术开发有限公司，研发MS-13X填充柱测定煤气中气体O2,N2,CH4,CO，柱效高，分离好，结果满意。

Gas Chromatographic Analysis of Artificial Gas Composition
Gas chromatographic analysis of artificial gas composition Details:

Name: Packed column

Specification: 3m*1/8

Model: MS-13X

Application: Application in total gas analysis O2, N2, CH4, CO measurement

At present, when using gas chromatographs to analyze the composition of artificial gas at home and abroad, most of them use multiple machines and combined columns to complete the analysis. The National Standards for Gas Chromatography Analysis Method of Artificial Gas Components in Urban Gas in my country stipulate the analysis of 10 main components such as hydrogen, oxygen, nitrogen, carbon monoxide, carbon dioxide, methane, ethylene, ethane, propylene and propane.

So far, in gas chromatographic analysis at home and abroad, almost all 5A (or 13X) molecular sieves are used as the stationary phase. Its disadvantage is that the separation efficiency drops rapidly when it encounters water, and it can permanently adsorb CO 2 and almost all organic compounds at room temperature and become poisoned. Therefore, the performance of this stationary phase is always in the process of change during use, which brings a lot of difficulties to quantitative work.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has developed MS-13X packed column for the determination of permanent gases O2, N2, CH4, CO in coal gas, with high column efficiency, good separation, and satisfactory results.
