在气液色谱法中,关于如何选择固定相,提高柱的分离能力已有人总结了一些普遍规律。但对于异构物的分析来说,现有的几个规律有时不够全面。本文通过六六六各异构体的分离来探讨分子结构对分离的影响。一、理论探讨气液色谱中物质的保留体积V_R值取决于固定相分子与溶质分子间的作用力。这种作用力主要有范德华力、氢键及电子转移络合作用。色谱工作者过去一般根据这些力来分析、讨论物质的出峰时
In gas-liquid chromatography, some general rules have been summarized on how to select the stationary phase and improve the column separation ability. But for the analysis of isomers, the existing laws are sometimes not comprehensive enough. In this paper, the separation of hexacosanil isomers to explore the impact of molecular structure on the separation. First, the theoretical discussion Gas-liquid chromatography in the retention volume V_R value depends on the interaction between the stationary phase molecules and solute molecules. This force is mainly van der Waals forces, hydrogen bonding and electron transfer complex. Chromatographers used to be based on these forces to analyze the past, when the material peak
