This webinar will provide a quick introduction to the basics of UV, dRI, MALS, and intrinsic viscosity detection for size exclusion chromatography (SEC).  Applications covered will include the determination of molecular weight by UV or dRI (differential refractive index) and MALS (multi-angle light scattering),  measurement of the degree of PEGylation with UV, dRI and MALS, and elucidation of structural and hydrodynamic properties using IV (intrinsic viscosity) and MALS.
