SEC-MALS to determine chitosan molar mass

AN1307: SEC-MALS analysis of cellulose/DMAC molecular weight distributions Introduction Cellulose, a biopolymer of great importance to the fiber and paper industries, is difficult to characterize because of its high molar mass. Its intractable nature means it cannot be dissolved in…

AN1305: Irradiation-Induced Degradation of Sodium Alginate Studied by SEC-MALS Summary Sodium alginates are widely used as a food additive or as a sterile wound dressing. The molecular weight and conformation properties of this polysaccharide contribute directly to their end-use performance.…
