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