Simple chromatography is carried out on paper – a spot of the mixture is placed near the bottom of a piece of chromatography paper and the paper is then placed upright in a suitable solvent.

Different chromatograms and the separated components of the mixtures can be identified by calculating the Rf value

Rf = distance moved by the compound ÷ distance moved by the solvent
