Summary An aqueous size exclusion chromatography system is outlined using dual detection by a multi-angel laser light scattering photometer (MALLS) and a concentration detector (RI). This system makes possible the determination of the molecular weight distribution of water soluble polymers in conjunction with the radius of gyration. The differences in the radii of gyration at the same molecular weights of two hydroxyethyl starches with different molecular structure are presented qualitatively. The determination of the Mark-Houwink relation for these polymers leads to a qualitatively similar result.
