what is the difference between thin layer chromatography and paper chromatography?
Thin layer chromatography(TLC) is a chromatography technique used to separate mixturesThin layer chromatography is performed on a sheet of glass, plastic, or aluminum foil, which is coated with the a thin layer of adsorbent material, usually silica gel, aluminium oxide, or celluloseThis layer of adsorbent is known as the stationary phaseAfter the sample has been applied on the plate, a solvent or solvent mixture (known as the mobile phase) is drawn up the plate via capillary actionBecause different analytes ascend the TLC plate at different rates, separation is achieved.
