Type of chromatography
Stationary phase – Cellulose paper absorb layer of aqueous water (liquid phase)
Stationary phase – Solid silica SiO2 or alumina AI2O3 (solid phase)
Stationary phase –Solid silica SiO2 or alumina AI2O3 packed in column(solid phase)

Type of chromatography
Stationary phase – Cellulose paper absorb layer of aqueous water (liquid phase)
Stationary phase – Solid silica SiO2 or alumina AI2O3 (solid phase)
Stationary phase –Solid silica SiO2 or alumina AI2O3 packed in column(solid phase)
Mobile phase is liquid solvent Mobile phase is liquid solvent Mobile phase is liquid solvent

Stationary phase –Solid silica SiO2 or alumina AI2O3 packed in column(solid phase)
Mobile phase is liquid solvent Mobile phase is liquid solvent Mobile phase is liquid solvent
Solvent moves by capillary actionPartition/Distribution of solutebetween 2 liquid phase
Adsorption of solute onto Stationary solid phase
Adsorption of solute on Stationary phase- strongly adsorp – travel slowly (eluted last)- weakly adsorp – travel fast (eluted first)
