Zeta potential is a measure of the magnitude of the electrostatic or charge repulsion/attraction between particles, and is one of the fundamental parameters known to affect stability. Its measurement brings detailed insight into the causes of dispersion, aggregation or flocculation, and can be applied to improve the formulation of dispersions, emulsions and suspensions.

Speed of introduction of new formulations is the key to product success. Measurement of zeta potential is one of the ways to shorten stability testing by reducing the number of candidate formulations, hence reducing the time and cost of testing as well as improving shelf life.

In water treatment, monitoring dosage using zeta potential measurements can reduce the cost of chemical additives by optimizing the dosage control.

The measurement of zeta potential has important applications in a wide range of industries including; ceramics, pharmaceuticals, medicine, mineral processing, electronics and water treatment.

Malvern Instruments offer leading instrumentation for the measuring of zeta potential, or electrophoretic mobility. The Zetasizer Nano provides a simple, fast and accurate way to measure zeta potential, and uses a unique disposable capillary cell to ensure that there is no cross contamination between samples. The NanoSight NS500 measures single particle zeta potential distributions which can be measured simultaneously with particle size, concentration and when operating in fluorescence mode.
