Epoxy resin (jER1009) was analyzed using GPC HK series, organic SEC (GPC) columns for ultra-rapid analysis. When analyzing low molecular weight samples, the separation of the lower molecular region becomes insufficient using only HK-404L, and a part of the sample overlaps the solvent peak (vacant peak). When HK-401 which is specialized for separation of low molecular weight regions, is connected with HK-404L in series, the analysis of the broad range from high molecular weight to low molecular weight can be achieved.
