The separation of polystyrene and the calculation result of molecular weight distribution of styrene butyl methacrylate copolymer using GPC HK-404L, an organic SEC (GPC) column for ultra-rapid analysis, were compared with a conventional device and a semi-micro type device. It was confirmed that the separation and the calculation result of molecular weight distribution are similar. HK-404L can be also used with the conventional device.
