Recruitment Learning – An Introductions principally by electrostatic forces. The newer technique of gel chromatography (gel filtration), where the stationary phase is a porous gel and the separation is according to molecular size, is included in this chapter because the methods used are commonly those of conventional column chromatography.

Consden, Gordon and Martin[l] in 1944 separated the amino-acids and peptides in wool protein hydrolysates by a method in which the powder column was replaced by a sheet or strip of paper, freely suspended in a vapour-tight vessel.

Thin-layer Chromatography,d as a binder. The strips were handled in the same way that paper is handled in paper chromatography, and indeed the original object of the thin-layer technique was to apply the methods of paper partition chromatography to an adsorption system.
