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 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.
