Epoxy Resin (7) ( Effects of Flow Rate for HK-402)


GPC HK-400 series, organic SEC (GPC) columns for ultra-rapid analysis  have low column pressure even at high flow rates and can be used in conventional HPLC device. The separation of epoxy resin (jER1001) using HK-402 was compared at flow rates of 0.3 mL/min and 1.0 mL/min. At a flow rate of 1.0 mL/min, equivalent separation can be achieved with an analysis time of 1/6 or less of a conventional SEC column, but if separation is important, it is recommended to analyze at 0.3 mL/min. (Even at 0.3 mL/min, the analysis time is less than half that of a conventional SEC column.)
