A Coincidence Technique for Paper Chromatography

Abstract

IN paper chromatography, the RF value, or ratio of distance travelled by substance to the distance travelled by solvent front, is generally used as the criterion of identity. If two substances have the same RF values in two or more solvent systems, they are assumed to be identical. But although RF values are often quoted with great precision, experience shows that they are, at best, only a rough guide and should not be used as the sole means of identifying a substance.
