The Malvern Zetasizer series measures particle and molecule size from below a nanometer to several microns using dynamic light scattering, zeta potential and electrophoretic mobility using electrophoretic light scattering, and molecular weight using static light scattering. In addition the system can be connected to a GPC / SEC system to use as a chromatography detector. The system is available in a range of variants that allows you to select the best system for your application and budget, and the philosophy of the design is to ensure exceptional ease of use and give confidence in the results without compromising performance.
