Irradiation-induced degradation of sodium alginate studied by SEC-MALS
3 Feb 2025Explore the impact of gamma irradiation on sodium alginate, a polysaccharide widely used in food and medical applications. Using SEC-MALS with a DAWN™ multi-angle light scattering detector and Optilab™ refractometer, researchers can determine molecular weight, size, and conformation without relying on column calibration assumptions. Understanding these properties is crucial for optimizing sodium alginate's performance as a thickening agent and sterile wound dressing.
