The effect of flow rate was examined for organic solvent SEC (GPC) semi-micro columns,
KF-402HQ and
KF-403HQ.
Improved separation is observed at lower flow rate, especially for the analysis of large MW compound such as EPON1001. Please see
Effects of flow rate (1) (KF-402HQ)
for an additional information.
Sample : 0.2% EPON1004, 10µ L
Column : Shodex GPC KF-403HQ + KF-402.5HQ (4.6mmID*250mm each)
Eluent : THF
Detector : Shodex RI (small cell volume)
Column temp. : 40° C
