On what principle sublimation and chromatography is based

Open in App
Solution

Definition & Principle in chromatography.
It is defined as the process of separation of the individual components of a mixture based on their relative affinities towards stationary and mobile phases.
Principle: The samples are subjected to flow by mobile liquid onto or through the stable stationary phase.
Sublimation is a process in which a solid turns directly into gas without passing into liquid state.
It works on the principle that solids have a weak intermolecular force hence a higher vapour pressure which converts it into directly vapour state. It is applicable in forensic science, purification of compounds and frost-free refrigeration.
