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.
