IN the preface to the first edition of one of the earliest books on chromatography, Principles and Practice of Chromatography (Zechmeister and Cholnoky, 1943) there is written: “Every scientific advance is an advance in method.” It is also stated in this prefcice that “the invention of a new specialized laboratory procedure brings about rapid conquests in new fields of science and technology, finally it exhausts itself and is replaced by a still more practical method. The method of chromatographic adsorption invented by the talented Russian botanist, Professor M. Tswett makes possible spatial separation of components of a mixture. It is just now at the beginning of a bullish development : it offers a simple experimental procedure to the investigator especially in the fields of both pure and applied organic chemistry, of biochemistry and of physiology.”
