Nanoparticle Size Analyzer with Zeta Potential

Malvern Zetasizer Nano ZS 90

The Malvern Zetasizer provides exceptionally high performance that incorporate combinations of a particle size analyzer, zeta potential analyzer. Particles from less than a nanometer in size to several microns can be analyzed by a range of variants. The systems measure size using dynamic light scattering, zeta potential using electrophoretic light scattering, and molecular weight using static light scattering. Zetasizer Nano ZS 90 Nanoparticle Size Analyzer is used for routine measurements of particle size distributions from about 1 nm to about 6 nm in any liquid by using Dynamic Light Scattering (DLS). Options also include full zeta potential capability and higher power lasers for very small particle sizes. Dynamic Light Scattering (DLS) provides a fast, simple method for submicron particle sizing. In this technique, random intensity fluctuations arising from the Brownian motion of colloidal particles are analyzed by autocorrelation to give both a simple mean size and polydispersity (distribution width) or more complete distribution data even for multimodal distributions.
