Comparison of Calibration Curves for Down-sized SEC Columns (HFIP Eluent: PMMA)

The calibration curves for downsized organic SEC (GPC) columns using PMMA are shown. In the case of the analysis for polymer whose MW is 1,000,000 or less, GPC LF-604 or LF-404 is suitable. When it is needed to separate low MW polymer and high MW polymer and low MW polymer is the purpose for the analysis, GPC HFIP-603 is suitable.
