OVERVIEW

Successful analysis of lignocellulosic biomass and biomass derivatives by conventional physico-chemical techniques can prove a formidable task. A suite of tools based on static multi-angle light scattering (MALS) and dynamic light scattering (DLS) for absolute determination of molar mass, size and conformation successfully addresses the characterization of these challenging macromolecular solutions and nanoparticle dispersions.

The webinar will present a brief introduction to MALS, DLS and ancillary technologies, as well as case studies that demonstrate the application of light scattering and related experimental techniques to overcome obstacles commonly encountered with difficult-to- analyze samples such as lignins and nanocrystalline cellulose.

KEY LEARNING OBJECTIVES:

- How light scattering addresses common problems in lignin analysis such as aggregation, fluorescence, and column adsorption.

- How light scattering determines the shape and length of nanocrystalline cellulose.

- How asymmetrical field flow fractionation can be more effective than GPC for separating larger nanoparticles and hyper-branched or sticky polymers.

- The use of differential viscometry coupled with MALS to provide insights into polymer density and conformation.

- How to measure the electrophoretic mobility and zeta potential of lignocellulosic samples in solution.
