What is Paper Chromatography? Definition and Meaning

 Definition of Paper Chromatography:

Paper chromatography is a chromatographic technique in which components of a mixture are separated on a sheet of paper using a liquid mobile phase. In this method, the paper functions as the stationary support while a liquid solvent moves across it to enable separation. The technique requires direct interaction between the paper medium and a liquid phase for separation to occur. Separation is defined by taking place on the paper surface itself rather than within columns, coated plates, or gaseous systems.
