Chromatography
Chromatography is an important technique extensively used to separate mixtures into their components, purify compounds, and also to test the purity of compounds.
Paper chromatography
“Partition chromatography is based on the continuous differential partitioning of components of a mixture between stationary and mobile phases.”
Paper chromatography is a type of partition chromatography.
Chromatography paper is a unique kind of paper that is used in paper chromatography. Water that has been trapped inside a chromatography paper serves as the stationary phase.
A strip of chromatography paper that has been smeared at the base with the mixture's solution is suspended in an appropriate solvent or a combination of solvents. The mobile phase is this solvent.
Capillary action causes the solvent to ascend up the paper and run over the spot.
So, the principle involved in paper chromatography is partition.
