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.

Quantitative Paper Chromatography

Nature, 1949
Fisher, Parsons and Morrison1 have shown experimentally that a linear relation holds between the area of the spot of test substance and the logarithm of the concentration at which it is originally applied. A theoretical derivation can now be given.

Paper Chromatography of Pterins

Nature, 1949
THE detection and identification of pterins in small quantities was carried out by Schopf and Becker1 in the course of their classical work on this class of pigments. They employed a chromatographic technique using 0·004 N aqueous hydrochloric acid or 0·01 N methyl alcoholic hydrochloric acid solutions on micro-absorption columns of alumina or ...
