Chromatography depends on the idea of partition coefficient. Any solute segments between two immiscible solvents. When we make one dissolvable immobile (by adsorption on a solid support matrix) and another mobile it brings about most basic utilizations of chromatography. If the matrix support, or stationary phase, is polar (e.g. paper, silica and so forth.) it is forward stage chromatography, and if it is non-polar (C-18) it is reverse phase. A portion of the top Techniques by chromatographic bed shape are Column chromatography, Planar chromatography, Gas chromatography, Liquid chromatography, Supercritical liquid chromatography, Ion trade chromatography, Size-prohibition chromatography, Expanded bed adsorption chromatographic partition.
