Particle size measurement has become a critical application for chemicals, foods, paints, cosmetics, coatings, materials, and many other industries. Particle size, shape, density, and distribution affect the physical properties and chemical behavior

Currently nanoparticles are measured by most particle size analyzers using scattered light; however in some cases this presents many physical restrictions and also requires the input of the refractive index as a measurement condition.

The majority of the zetameters are based on the electrophoresis measuring principle where the zeta potential for a colloidal system is analyzed by measurement of the electrophoretic mobility of the particles.

From millimeters to sub-nanometers, accurately measuring particle size is essential in determining the usefulness and performance characteristics of a material.
