摘要

9 月 22 日至 24 日，法拉第协会在雷丁大学举行了题为 "色谱分析 "的全球讨论会，约翰-伦纳德-琼斯爵士主持了会议。会议首先由 A. Tiselius 教授致开幕词，他简要总结了色谱法的早期工作以及目前用于分离无机和有机材料的现代方法。他指出了克雷格逆流提取法的价值，并讨论了正面分析、洗脱分析和置换分析的优缺点。他还评论了一个重要的观察结果，即二氧化硅在与甲基橙共沉淀时会成为该指示剂的特异性吸附剂。这样，就有了一种新的特异性物质分离方法。

Chromatographic Analysis

A GENERAL discussion on "Chromatographic Analysis was held by the Faraday Society at the University of Reading during September 22–24, with Sir John Lennard-Jones in the chair. The programme began with an introductory address by Prof. A. Tiselius who gave a brief summary of the earlier work on chromatography and on the modern methods which are now used to separate inorganic and organic materials. He pointed out the value of the counter-current extraction method of Craig and discussed the advantages and disadvantages of frontal, elution and displacement analysis. He also commented on the important observation that silica becomes a specific adsorbent for methyl orange when it is co-precipitated with this indicator. A new specific method for the isolation of substances thus becomes available.
