Two kinds of epoxy resin, epokote 1001 and epikote 1004 were analysed using conventional type GPC column (GPC KF-803L) and downsized 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.
