Characterizing polysaccharide structure with SEC-MALS and intrinsic viscosity measurements

| Sponsored by Malvern Panalytical

In this application note, molecular weight data from the Viscotek SEC-MALS 20 is combined with measurements of Rg and IV to study the structure of different polysaccharides including pullulan, dextran, hydroxypropyl cellulose (HPC), pectin and gum Arabic. The differences between conformation and Mark-Houwink plots are also studied.
