Gel Permeation Chromatography (GPC)


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.

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.
