About Paper Chromatography

Chromatography method that uses paper sheets or strips as the adsorbent is called paper chromatography and is the stationary process in which a solution is allowed to move. It is a cheap way of distinguishing dissolved chemical compounds by their varying patterns of movement through paper sheets. It is a versatile analytical method that makes use of very small quantities of information. In the year 1943 Synge and Martin invented paper chromatography.

The theory concerned can be chromatography for partitioning or chromatography for adsorption. Chromatography partitioning as the compounds are separated or dispersed between the layers of liquids. The two stages are water that is placed in filter paper pores, and the other phase is a fluid stream that goes through the surface. The division of mixture happens as the mobile phase shifts. The compounds in the mixture distinguish under the capillary action of pores in the paper, depending on the variations in their affinity to stationary and mobile phase solvents. Chromatography of adsorption into solid and liquid phases, of which the rigid portion of the material is the stationary and the liquid phase is the mobile phase.
