Characterization techniques based on multi-angle light scattering with chromatography (SEC-MALS) or field-flow fractionation (FFF-MALS) address many of the key analytical challenges in the modern polymer laboratory. This seminar will review light scattering technology, instrumentation, and applications to polymer research.
LEARNING OBJECTIVES:
-
Principles of MALS detection and calculation of polymer molecular size and mass
-
Identifying and overcoming shortfalls of conventional GPC/SEC via SEC-MALS
-
Leveraging DLS and intrinsic viscosity for enhanced characterization of molecular size
-
Calculation of copolymer ratios and molecular weights in-line with SEC
-
Advantages of FFF for separation of branched polymers
