Paper chromatography is an analytical technique for separating and identifying pigments and other molecule from extracts that contain a complex mixture of molecules. It is one of the frequently used forms of chromatography. The solvent moves up the paper by capillary action, which occurs as a result of the attraction of the solvent molecules to the paper and to one another. As the solvent moves up the paper, it carries along any substance dissolved in it. ...

| paper chromatography |
is a technique for analysing mixtures by chromatography, in which the stationary phase is the layer of water on the absorbent paper. After the mixture has been spotted at the bottom of the paper, solvent is allowed to rise up the paper by capillary action to some arbitrary height. The paper is then dried, and the individual components are identified by physical (eg ultraviolet light) or chemical (eg some chemical spray) methods. Thin Layer Chromatography, TLC,
