Quantitative Paper Chromatography

Nature, 1948
WE have recently developed a simple method for quantitative assay of amino-acids on the paper partition chromatogram. The method is in all probability applicable to any class of substance which can be readily located by means of a sensitive colourreaction on paper. Several technical points of general interest have arisen in the course of the work.
