Paper chromatography is a technique used for the separation of dissolved chemical substances by taking advantage of their different rates of migration on the paper sheet. It is an inexpensive and powerful analytical method that requires a very small amount of substance for the separation. Paper chromatography works on the principle of partition. The paper acts as a stationary phase, and the solvent in which the paper is immersed acts as a mobile phase that separates the components of the sample.

In this method, the sample or substance is applied as a fine spot at the bottom of the paper. This paper is immersed in the solvent in which the components of the mixture are soluble in varying degrees. The solvent penetrates over the paper via capillary action. It passes over the sample spot and carries over the soluble components along with it. The substance moves with the solvent at different velocities depending on its solubility in that solvent.

The locations of separated components are identified by applying the reagents that form the coloured compounds with the separated substances. For example, in the separation of a mixture of amino acids, a Ninhydrin reagent is applied. Amino acids show different colours with a Ninhydrin reagent.
