Abstract
WHEN information concerning the structure of substances is required from paper Chromatographic data, R M values are used rather than R F as they are more directly related to the different groups of which the molecules of these substances are composed1. In cases when one phase forming the Chromatographic system is composed of two solvents practically immiscible with the other liquid phase, at any proportion of the component solvents (for example, hexane + chloroform/water; hexane/water + di-methylsulphoxide) and assuming that chromatography is a true counter-current extraction process, following the plate theory, a simple equation can be derived relating the R M value to the composition of the two-component phase.
