Electrophoretic Light Scattering (ELS) is a technique used to measure the electrophoretic mobility of particles or molecules in solution. This measurement is used to determine Zeta potential, which is a measure of the electrostatic or charge repulsion/attraction between particles, and is a predictor of emulsion and dispersion stability. Zeta potential is a function of both the particle surface and the dispersant. It provides information that is critical to formulators during the design of multicomponent products.
In this presentation Dr Ana Morfesis will discuss the importance of Zeta potential measurements for colloidal dispersions and how it is determined using ELS.
