All particles in suspension have a zeta potential, or surface potential. Its measurement is extremely important for predicting the formulation stability across a wide range of industries including food, ink and pharmaceuticals, water purification and medical devices.

Zeta potential is not measurable directly but it can be calculated from an experimentally determined electrophoretic mobility. Unfortunately, the conversion between mobility and zeta-potential is neither straightforward nor undisputed. Here we use COMSOL to explore this problem, and compare with prevailing solutions.
