The Malvern Zetasizer range provides both exceptionally high performance and entry level systems that incorporate combinations of a particle size analyzer, zeta potential analyzer, molecular weight analyzer, protein mobility and microrheology measurements. Particles and molecules from less than a nanometer in size to several microns can be analyzed by a range of variants to suit your applications and budget.

The systems measure size and microrheology 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 used in a flow configuration to connect to a GPC / SEC system for use as a chromatography size detector.

How Do I Verify My Zeta Potential Instrument? FAQ

Electrophoretic light scattering (ELS) or zeta potential instruments use first principles in their measurement protocol. They cannot therefore, be calibrated. However, they can be verified that they are operating correctly, by measuring a suitable zeta potential standard.



How Do I Dilute My Samples For Zeta Potential Measurements? FAQ

Samples for zeta potential measurements need to be optically clear and may require dilution. The way in which the dilution is performed is absolutely critical in determining the zeta potential value measured.



What is Multiple Scattering? FAQ

Multiple scattering refers to the phenomenon where photons scattered from the sample are re-scattered from neighboring particles prior to reaching the instrument detector.



What is a Correlation Function (Correlogram)? FAQ

A correlation function shows the correlation coefficients plotted as a function of delay time
