Quick and Easy Membrane Characterization with Size Exclusion Chromatography

Size exclusion chromatography (SEC) is a powerful tool for the characterization of molecules differing in size and molar mass. It is widely used and well known for the determination of molar mass distributions and molar mass averages. For membranes GPC/SEC is a useful characterization method as it can measure the membrane characteristic pore size distribution, average pore size and molecular cut-off significantly faster than other methods.
