Description
Gel permeation chromatography (GPC) is a termused for when the separation technique size exclusion chromatography (SEC). GPC is often used to determined the relative molecular weight of polymer. Multiangle light scattering (MALS) is a technique for determining, independently, the absolute molar mass and the average size of particles in solution, by detecting how they scatter light.
