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.

Size: What is the z-average? FAQ

The z-average diameter is the mean intensity diameter i.e. it is a diameter based upon the intensity of scattered light of a material in its native state (including electrical double layers and surface structure). The z-average is derived from a Cumulants analysis of the measured correlation curve, wherein a single particle size is assumed and a single exponential fit is applied to the autocorrelation function. It is unique to dynamic light scattering and it is sensitive to the presence of aggregates/dust due to the intensity of light scattered by any larger particles present.
