Description:
The Zetasizer Nano ZS is a high performance two angle particle and molecular size
analyzer for the enhanced detection of aggregates and measurement of small or dilute
samples, and samples at very low or high concentration using dynamic light scattering
with ‘NIBS’ optics. The ZSP also incorporates a zeta potential analyzer that uses
electrophoretic light scattering for particles, molecules and surfaces, and a molecular
weight analyzer using static light scattering.
