Epoxy resin was analyzed using  GPC HK-402, an organic SEC (GPC) column for ultra-rapid analysis, and GPC KF-802.5 which is a conventional type column supports similar target molecular weight range for HK-402. When using HK-402 at the same flow rate as the conventinal type column, the same separation can be obtained in less than 1/6 of the analysis time. The HK-400 series has a low column pressure even at high flow rates and can be used in conventional HPLC device.
