Question

What criterion is followed for the selection of the stationary phase in chromatography?

Answer 1

Hey Dear,

# Criteria followed for selection of the stationary phase in chromatography -

1. Components of sample must have diff solubilities in the phase.
2. Impurities should be adsorbed more than desired element.
3. Components of solvent should have variable rates of movement through stationary phase.
4. Stationary phase should allow selective adsorption of certain substances.

Hope this helps you...

Answer 2

Components of sample must have diff solubilities in the phase. Impurities should be adsorbed more than desired element. Components of solvent should have variable rates of movement through stationary phase. Stationary phase should allow selective adsorption of certain substances.
