Nylon 6/9 was analyzed using GPC HK-HFIP404L, an organic SEC (GPC) column for ultra-rapid analysis. HK-HFIP404L can achieve approximately half of the analysis time compared with standard columns (8mmI.D. x 300mm) and the amount HFIP used can be greatly reduced to about a sixth. Since HFIP is very expensive, not only environmental concerns but also the burden of analysis costs can be reduced.
