Chromatographic Analysis

Abstract

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.
