Gel permeation chromatography/size exclusion chromatography (GPC/SEC) is a well-known technique for the separation of macromolecules like natural and synthetic polymers. It is the method of choice for the characterization of polymer molecular weight and molecular weight distribution. The EcoSEC GPC System is a dedicated GPC instrument developed for fast polymer analysis.
