The comparison of Asahipak GF-310 HQ (an Aqueous/Organic (multi-solvent use) SEC column) and an ODS column when they were used for the measurement of POE distribution of octylphenol ethoxylate is shown here. When GF-310 HQ was used, good chromatograms were obtained using 35 and 40 % acetonitrile concentration. On the other hand, when an ODS column was used, POE distribution can be measured using 55 % acetonitrile concentration but the separation is not sufficient.
