The Zetasizer Nano ZS is the top of the Zetasizer range and is particularly suitable where there are a wide range of applications and the highest performance is required. It includes 2 angle size measurement for the enhanced detection of aggregates, measurement of small or dilute samples, or at high concentration, zeta potential and electrophoretic mobility measurement, plus molecular size and molecular weight measurement. The system can be connected to an GPC / SEC system to use as a chromatography detector.

Size measurement from 0.3nm (diameter) to 10 microns using patented NIBS (Non-Invasive Back Scatter) technology

Zeta potential of proteins and particles from 3.8nm up to 100 microns (diameter) using patented M3-PALS technology

Molecular weight measurement down to 980Da

Sample concentrations from 0.1ppm to 40%w/v

Protein size measurement as dilute as 0.1mg/mL (Lysozyme)

A Quality Factor gives confidence in the data

The Expert advice report gives help to improve sample preparation or the measurement procedure

21CFR part 11 software option enables compliance with ER/ES

Research software option gives access to further features and analysis algorithms for the light scattering specialist

Automation of measurements using an autotitrator option

Flow mode capability to enable use as a GPC / SEC detector

Alternative laser, 50mW at 532nm for samples incompatible with the standard 633nm laser fitted

Optical filter option to improve measurements with fluorescent sample

Temperature range extension option to 120ºC
