English Abstract

Molecular Characterization of Polymer through SEC and Other Several Methods Eiichi TAKATORI Tosoh Analysis and Research Center Kasumi, Yokkaichi, Mie, Japan Nippon Gomu Kyokaishi,(2009),82(4),175-182 General Review in Japanese Abstract Fractionation technique is very significant for the polymer analysis. Several methods were proposed, SEC(Size Exclusion Chromatography), FFF(Field Flow Fractionation), Electrophoresis, Hydrodynamic Chromatography, MTF (Molecular Topology Fractionation), and so on. In these methods SEC is the most general. This report reviews about concepts of separation mechanism, sources of analytical error, detectors, and analysis examples of SEC. Keywords: Fractionation, SEC, Detector, Light Scattering, Viscometry, Mass Spectroscopy
