Structural Characterization of Functional Polymers via Light Scattering and Differential Viscometry

Webinar Date
  • Wed July 31, 2024
    11:00 AM 1 hour

Understanding the structure-function relationship of polymers is of critical importance for successful incorporation into commercial applications. In this webinar, Nemal Gobalasingham, Ph.D. will explore polymer characterization by multi-angle light scattering (MALS) and differential viscometry, coupled with size-exclusion chromatography or field-flow fractionation, for enhanced studies of polymer structure-function.

Case studies will illustrate the use of these analytical tools to unlock detailed information about molar mass distributions, size, structural conformation, and composition of a variety of functional polymers. Examples include nonwoven polymer fibers, formulation polymers, polymers for microneedles and polymers for other practical applications, all of which are often challenging to characterize fully by other methods.

By attending this webinar, you will learn:

  • Separation principles of size exclusion chromatography (SEC) and asymmetric flow field flow fractionation (AF4).
  • Theoretical background of multi-angle light scattering (MALS) detector and intrinsic viscosity (IV).
  • Determination of molar mass distributions, structural conformation, branching content, and other structural information in functional polymers using SEC-MALS-IV and FFF-MALS. 

Who should attend this event?

  • Polymer chemists seeking advanced analytical characterization capabilities
  • Researchers involved in synthetic, biopolymer, and functional polymer characterization
  • Scientists interested in the characterization of non-biological materials utilized in conjunction with biomedical applications
