The Dynamic Light Scattering instrument applied by Particle Analytical (Malvern Nano Zetasizer) measures the particle size distribution using laser dynamic light scattering and analysis of the Brownian motions of particles in the media. An electric field is applied to a solution of molecules or a dispersion of particles, which then move with a velocity related to their zeta potential.

Laser Doppler Micro-electrophoresis is used to measure zeta potential.

This technique measures the diffusion of particles moving under Brownian motion and converts this to size and a size distribution using the Stokes-Einstein relationship. The Dynamic Light Scattering instrument at Particle Analytical is a Nano Zetasizer, where both particle size and zeta-potential can be measured: The effect of temperature on particle size and stability can be investigated.
