The industrial hydrogen analysis project follows the national standard (GB/T3634.1-2006) The determination of oxygen, argon, and nitrogen content is carried out using gas chromatography, equipped with a deoxygenation column and a switching column for two injections. The content of argon and nitrogen in the sample gas is measured, and the sample is calculated by subtraction This party has manually injected samples twice, and each time the sample is analyzed in the quantitative tube of the six way valve. Due to different temperature and pressure, the analysis results are subject to human error

　　Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a special packed chromatography column for argon oxygen nitrogen separation in industrial hydrogen. With one injection, the column has high efficiency, good separation of O2, Ar, and nitrogen, symmetrical peak shapes, and short analysis time.

　　Name: Industrial hydrogen oxygen argon separation special column

　　Fixed phase: Dedicated

　　Specification: 3m * 1/8

　　Model: HH-ARO2-III

　　Application: Separation of oxygen, argon, and nitrogen in industrial hydrogen

　　工业氢气分析项目执行国家标准(GB/T3634.1—2006).其中氧、氩和氮含量的测定采用的是气相色谱法,配备脱氧柱和切换柱两次进样,测定样品气中氩和氮的含量,用差减法计算出样品.此方法人为地两次手动进样,每次分析样品在六通阀的定量管中由于受温度压力不同给分析结果带来人为误差

　　浩瀚色谱（山东）应用技术开发有限公司，研制的《工业氢中氩氧氮分离专用填充色谱柱》，1次进样，柱效高，O2，Ar，氮分离好，峰型对称，分析时间短。

　　名称:工业氢中氧氩分离专用柱

　　固定相:专用

　　规格:3m*1/8

　　型号:HH-ARO2-III

　　应用:工业氢中氧，氩，氮的分离
