The effect of temperature when POE distribution of octylphenyl ethoxylate (n=6) is measured using Asahipak GF-310 HQ (an Aqueous/Organic (multi-solvent use) SEC column) is shown here. Over the wide temperature range, good chromatograms are obtained. At high temperature, higher resolution is obtained because of sharp peak shape though the retention time is faster.
