The stationary phase is an adsorbent and has following characteristics:
(1) Its adsorption power should be high and selective.
(2) To offer greater surface area for adsorption, it should be finely divided.
(3) It should have high mechanical stability. This will prevent dust formation.
(4) It should be chemically inert to sample and eluting solvents.
(5) It should have high purity.
