Quantitative Paper Chromatography based on the Sub-Micro Titration of Derivatives containing Nitro Groups

Abstract

AN extensive literature on the quantitative paper chromatography of a large variety of organic compounds already exists. Most of these methods are based on: (a) measurement of the optical density of a coloured spot produced on the paper chromatogram by spraying with a suitable reagent; or (b) measurement of the optical density (in ultra-violet or visible light) of an extract of the component considered, after separation from other components by paper chromatography.
