Dynamic Light Scattering (DLS), sometimes referred to as Photon Correlation Spectroscopy or Quasi-Elastic Light Scattering, is a technique classically used for measuring the size of particles typically in the sub-micron region, dispersed in a liquid. The sensitivity of some modern systems is such that it can also now be used to measure the size of macromolecules in solution.
In this presentation Dr Mike Kaszuba will summarize how the technique works, what its size and concentration limits are, and discuss its advantages and disadvantages.
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.
