Triple Detection System

Viscotek has produced a new applications report illustrating how its Triple detection-GPC (SEC3) system enables precise and comprehensive characterisation of even complex polysaccharides. In the report two samples identified as branched polysaccharides and one sample identified as a corresponding linear polysaccharide are analysed to determine molecular weight and to analyse branching by the system. The polysaccharide samples in the report were analysed using the Viscotek system comprising low angle light scattering (LALS), refractive index and viscometry detectors working in concert. The report shows that both light scattering and viscometry data is required to unlock molecular weight distribution, viscosity, molecular size and branching frequency data from the highly branched samples.
