Light scattering is a fundamental analytical technique for the characterization of particulate materials, and is most commonly applied to colloidal systems, nanoparticles and acromolecules in solution or dispersion, to determine particle size and Zeta Potential. Malvern Particle Size and Zeta Potential Analyzer is used to measure particle and molecular size from less than a nanometre to several microns using dynamic light scattering and Zeta Potential by using electrophoretic light scattering.

The particle size analyzer is the ideal tool for sub-micron analysis of size and zeta potential of dispersed particles of mineral, chemical, ceramic, polymer, pharmaceutical and agricultural sciences.

The Zetasizer Nano ZS90 is the perfect lower cost solution when the ultimate in sizing sensitivity is not necessary, or where identical results to a legacy system with 90 degree scattering optics is required.
