Zeta Potential Light Scattering

Zeta potential is the charge on a particle at the shear plane. This value of surface charge is useful for understanding and predicting interactions between particles in suspension. Manipulating zeta potential is a method of enhancing suspension stability for formulation work, or speeding particle flocculation for water treatment for example. Measuring zeta potential by electrophoretic light scattering allows one to assess the effects of various strategies for manipulating zeta potential. Electrophoretic light scattering exploits the fact that a charged particle responds to an applied electric field.
