Epoxy Resin (1) (Comparison of KF-803L and KF-603 + KF-602.5)

Two kinds of epoxy resin, epokote 1001 and epikote 1004 were analysed using conventional type organic SEC (GPC) column (GPC KF-803L) and downsized organic SEC (GPC) columns (GPC KF-603 + KF-602.5). Using downsized GPC columns, better separation could be obtained in shorter time. For downsized GPC columns, an RI detector of small cell volume type was used.
