TDX-01 碳分子筛填充柱在高纯气体分析中的应用

名称：填充柱

型号：TDX-01

规格：2m*3mm，60-80目

高使用温度：240°C

浩瀚色谱（山东）应用技术开发有限公司建立了一种新型碳分子筛(TDX01)填充柱分析高纯氦中杂质组分的方法,该方法利用一根色谱柱完成高纯氦中所有杂质组分的分离,简化了分析气路流程,结果表明该方法具有重复性好(<2%),操作简便等特点。探讨应用tdx柱作为预柱在不同气体分析中的可行性,通过TDX与PQ柱作为预柱的对比实验表明TDX柱解决了PQ柱对低浓度氧气不可逆吸附的问题,对NH3、SF6、Si H4等气体分析应用表明TDX柱作预柱在基流稳定性和氧气分析方面较PQ柱有一定优势,但是也存在可能会与某些特定基底气反应及无法预分离等问题。

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has established a new type of carbon molecular sieve (TDX01) packed column method for the analysis of impurity components in high-purity helium. This method uses a chromatographic column to complete the analysis of all impurity components in high-purity helium. Separation simplifies the process of analyzing the gas path, and the results show that the method has the characteristics of good repeatability (<2%) and easy operation. Discuss the feasibility of using tdx column as a pre-column in the analysis of different gases. The comparative experiment of TDX and PQ column as pre-column shows that TDX column solves the problem of irreversible adsorption of low-concentration oxygen by PQ column. Other gas analysis applications show that TDX column as a pre-column has certain advantages over PQ column in terms of base flow stability and oxygen analysis, but there are also problems that may react with certain base gases and cannot be pre-separated.
