Gel Permeation Chromatography (GPC) is an analytical technique that separates dissolved macromolecules by size based on their elution from columns filled with a porous gel.
When GPC is coupled with light scattering, viscometer and concentration detectors (known as triple detection), it can measure absolute molecular weight, molecular size and intrinsic viscosity, and generate information on macromolecular structure, conformation, aggregation and branching.
By using GPC to measure molecular weight and these other properties, scientists can characterize molecules such as synthetic polymers, as well as natural polymers such as polysaccharides.
For all of these molecules, these parameters relate very closely to their performance in countless applications. With this technique:
From novel polymers to polymer formulations and additives, in applications from paints and coatings to foods and pharmaceuticals, Malvern offers a range of GPC systems or individual GPC detectors including SEC-MALS to suit your application needs.
