How does multi-detector GPC/SEC work?

Whether your samples are synthetic polymers, natural materials such as polysaccharides, or proteins, antibodies, or other biological samples, gel permeation / size exclusion chromatography (GPC/SEC) is the ideal technique for characterizing those and other types of macromolecules.  The information offered from…READ MORE >

Can GPC/SEC determine if my sample is branched?

While talking to customers about their samples, a frequent topic that comes up is whether or not their samples are branched.  Fortunately, I work primarily with Malvern Panalytical’s gel permeation / size exclusion chromatography (GPC/SEC) product range, which in addition…READ MORE >
