Chromatography;1.Production Chromatography is a kind of separation technique Tswett, Russia botanist founded Chromatography in 1906 year Separate pigment in leaves CaCO3 filled in the column adsorb pigments Mineral ether as mobile phase ;Experiment of Tsweet;In 1930, R.Kuhn and M.Tswett separate carotene In 1941, Martin and Synge separate amino acid mixture through column filled with silica gel. In 1952, Martin and Synge founded Gas-liquid Chromatography to Separate aliphatic acid. In 1956, Van Deemter develop Chromatography rate theory. In 1960,High pressure induced flow mobile phase. ;Devepment in our country;Chap 5 Gas Chromatography and Inverse Gas Chromatography;5.1 General Principles of Chromatography;5.1.1 Concept; Distribution coefficient K: CG:concentration of constituents in mobile phase.
