The particle size analyser is a 3000S with on line autotitrator. This instrument allows measurement of both particle size in the range 2 nm to 3 μm and zeta potential in the range 5 nm to 30 μm. Knowledge of the parameters of zeta potential and particle size is a powerful research and development tool for investigating the stability of dispersions and emulsions. Zeta potential is a measure of the magnitude of the repulsion or attraction between particles. Its measurement can provide detailed insight into the dispersion mechanism and is the key to electrostatic dispersion control. The zeta potential of a dispersion or emulsion is one of the major parameters that control dispersion stability. Monitoring this parameter can shorten product formulation times, identify the mechanisms responsible for a dispersion’s stability and enable optimisation of .occulation. The  measurement of particle size is an extremely important technique

in many industrial processes. The stability, chemical reactivity, opacity, viscosity and material strength of many materials are affected by the size and characteristics of the particles within them.
