Zetasizer

Model: Malvern Nano-ZS

Facility: Nanoscale Characterization Facility

Function: The Zetasizer Nano-ZS can measure (1) particle size of particles and molecules from 0.6 nm to 6 micrometers using non-invasive back-scatter (NIBS) technology and dynamic light scattering, (2) zeta potential in aqueous and non-aqueous dispersions using M3-PALS technology, and (3) molecular weight with an absolute measurement using static light scattering and the sensitivity from an avalanche-photodiode detector and fiber detection optics. The Nano-ZS can measure all three parameters with no performance compromises and allows measurements of samples with little or no dilution. The unique disposable zeta potential cell ensures no cross contamination of samples.
