名稱：填充柱

型號：TDX-01

規格：2m*3mm，60-80目

高使用溫度：240°C

浩瀚色譜（山東）應用技術開發有限公司建立了一種新型碳分子篩(TDX01)填充柱分析高純氦中雜質組分的方法,該方法利用一根色譜柱完成高純氦中所有雜質組分的分離,簡化了分析氣路流程,結果表明該方法具有重復性好(<2%),操作簡便等特點。探討應用tdx柱作為預柱在不同氣體分析中的可行性,通過TDX與PQ柱作為預柱的對比實驗表明TDX柱解決了PQ柱對低濃度氧氣不可逆吸附的問題,對NH3、SF6、Si H4等氣體分析應用表明TDX柱作預柱在基流穩定性和氧氣分析方面較PQ柱有一定優勢,但是也存在可能會與某些特定基底氣反應及無法預分離等問題。

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.
