Classification of Chromatographic Techniques
According to the Mode of Retention
1. Adsorption Chromatography. GSC
✓ Stationary phase: Solid.
✓ Mobile phase: Liquid or gaseous. LSC
✓ Physical property: Adsorption.
✓ Solute is adsorbed on the surface of the solid stationary
phase particles.
The more the affinity of a 50
molecule of a particular
component to stationary
phase, the less will be its
movement.
