Abstract
Chromatography is the name given to a technique for the analysis of mixtures by passage of their solutions through an adsorbent column. The different constituents adsorb at different rates, and advantage is taken of this property to separate the components into different sections of the column. |Schoenbein in 1861 was the first to show that, when aqueous solutions rise in strips of filter paper, the water precedes the dissolved material, and the relative height of ascent of solutes can differ enough to make it possible to detect the co—solutes in separate zones. He called this hew phenomenon "capillary analysis" and predicted its Usefulness in the field of analytical chemistry.
