In an interlaboratory study we compare different methods to determine the weight-average molecular weight (Mw) and distribution of six cereal beta-glucan isolates nutritional importance. Size-exclusion chromatography (SEC) with multi-angle light scattering (MALS), capillary viscometry, sedimentation velocity analytical ultracentrifugation one asymmetric flow field-flow fractionation (AF4)-MALS ...
