Despite the tremendous potential impact of his discovery, chromatography was not revived until 1931, under the stimulus of widespread research on the separation of carotenoids from several natural sources by adsorption analysis on fibrous alumina [4]. Since the cited work was published, chromatography application has been extended over practically all areas of chemistry. In polymer science, chromatography was used for the first time by Moore in 1963 to determine the MWD of polymers [5].
