Particion or ascending paper chromatography is used to separate coloured chemicals or substance. It is an analytical technique in which the mobile phase moves upward through the stationary phase. Mobile phase → Liquid (solvent) Stationary phase → Liquid (Whatmann, paper contain cellulose). While in gas-liquid chromatography, gas is stationary phase and liquid is mobile phase. TLC contain silica which is solid (stationary phase) and solvent (mobile phase).
