Determination of Keto-Acids by Partition Chromatography on Filter-Paper

Nature volume 163, pages 568–569 (1949)Cite this article

Abstract

THE method used by Consden, Gordon and Martin1 for the qualitative analysis of amino-acid mixtures, and by Partridge2 for sugars, employing filter-paper partition chromatography, was applied to the determination of some keto-acids. The keto-acids were characterized as their 2,4-dinitrophenyl. hydrazone derivatives ; this gave the advantage of manipulating coloured compounds, which showed their position on the paper without further development.
