According to its separation mechanism, liquid chromatography can be divided into four types: adsorption chromatography, partition chromatography, ion exchange chromatography, and gel chromatography.

UNDER the title “Partition Isotherms and Gas-Liquid Chromatography,” Freeguard and Stock 1 have reported that for all the systems studied by them, symmetrical elution peaks would be expected ...

SINCE the technique of paper partition chromatography is generally inapplicable to fat-soluble substances, we have investigated the use of alumina impregnated filter paper for this purpose. We ...
