Electrophoretic light scattering
- Electrophoretic light scattering
Electrophoretic light scattering is based on dynamic light scattering. The frequency shift or phase shift of an incident laser beam depends on the dispersed particles mobility. In the case of "dynamic light scattering", Brownian motion causes particles motion. In the case of "electrophoretic light scattering", oscillating electric field performs the same function.
This method is used for measuring electrophoretic mobility and then calculating zeta potential. Instruments to apply the method are commercially available under the name "zetasizer". The last set of calculations requires information on viscosity and dielectric permittivity of the dispersion medium. Appropriate electrophoresis theory is also required. Sample diltuin is necessary in order to eliminate particles interaction.
