(1) In paper chromatography, a special quality paper called chromatographic paper is used, Although paper consists mainly of cellulose. The stationary phase in paper chromatography is not the cellulose but the water which is adsorbed or chemically bound to it.
(2) The mobile phase is another liquid which is usually a mixture of two or three solvents with water as one of the components. It is a type of parition chromatography in which both the mobile phase and the stationary phase are liquids.
(3) Paper chromatography works on the principle of partition, i.e., it is based upon continuous differential partitioning or distribution of the various components of the mixture between the stationary and the mobile phase, here Recalled the retention factor is
