7. Partition Chromatography Adsorption Chromatography 2 Distribution of X, Y and Z between two liquid phases Adsorption of X, Y and Z onto SOLID phase

8. Type of chromatography

10. Stationary phase – Cellulose paper absorb layer of aqueous water (liquid phase) Stationary phase – Solid silica SiO 2 or alumina AI 2 O 3 (solid phase) Stationary phase – Solid silica SiO 2 or alumina AI 2 O 3 packed in column (solid phase)

11. Type of chromatography Stationary phase – Cellulose paper absorb layer of aqueous water (liquid phase) Stationary phase – Solid silica SiO 2 or alumina AI 2 O 3 (solid phase) Stationary phase – Solid silica SiO 2 or alumina AI 2 O 3 packed in column (solid phase) Mobile phase is liquid solvent

12. Type of chromatography Stationary phase – Cellulose paper absorb layer of aqueous water (liquid phase) Stationary phase – Solid silica SiO 2 or alumina AI 2 O 3 (solid phase) Stationary phase – Solid silica SiO 2 or alumina AI 2 O 3 packed in column (solid phase) Mobile phase is liquid solvent Solvent moves by capillary action Partition/Distribution of solute between 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)
