How to Measure Molecular Weight with Gel Permeation Chromatography (GPC)

So you have a new polymer, unknown protein, or material combination but don’t know its molecular weight? An easy way to measure molecular weight of your sample is gel permeation chromatography (GPC). GPC is an analytical technique that separates molecules in polymers by size and provides the molecular weight distribution of a material. GPC is…
