Course Description
The objectives of this short course are to discuss dynamic light scattering (DLS, PCS, QELS), molecular weight and electrophoretic light scattering (zeta potential) measurements. We will review dynamic light scattering theory, molecular weight determinations, provide useful tips for sample preparation and analysis of measurement results. DLS is a versatile and non-destructive measurement technique that is ideally suited as a metrology of choice for size, stability and identification of protein molecules, aggregates and particles over a wide range of materials in solution. We will also discuss electrophoretic light scattering measurements and the importance of zeta potential in understanding interfacial behaviour and the formulation of multi- component products.

Target Audience
Formulation scientists involved in the characterization of nanoparticles, proteins, biomolecules, liposomes, polymers, metal oxides, water treatment, nanotechnology and other material research applications. Anyone working in a field or application area that requires an understanding of particle size, molecular weight and formulation stability.
