Zetasizer Nano S: Dynamic Light Scattering System from Malvern Instruments

Zetasizer Nano S, a dynamic light scattering system from Malvern Instruments, combines the functions of both particle size analyzer and molecular weight analyzer. The system is user-friendly, versatile, and delivers high performance. It can be used for detecting aggregates, measuring dilute or high concentration samples, as well as for measuring molecular size and molecular weight.

The Zetasizer Nano S has the same sizing capability as the Zetasizer Nano Z and perfect for applications where the widest size range and highest sensitivity is required.

Key Features

The main features of the Zetasizer Nano S are:

  • Sample concentrations from 0.1 ppm to 40% w/v
  • Automated temperature trend measurements
  • Second virial coefficient measurement for solubility
  • Molecular weight measurement down to 980 Da.
  • Size measurement from 0.3 nm (diameter) to 10 µm using Non-Invasive Back Scatter (NIBS) technology
  • Alternative laser, 50 mW at 532 nm for samples incompatible with the usual 633 nm laser fitted
  • Autotitrator option allows automation of measurements
  • Optical filter option to enhance measurements with fluorescent sample
  • 21CFR part 11 software option allows compliance with ER/ES
  • Temperature range extension option to 120ºC
  • Systems can be upgraded to include zeta potential
  • Protein size measurement as dilute as 0.1 mg/mL (Lysozyme)
  • Flow mode capability to enable use as a GPC/SEC detector
  • Research software option offers access to additional features and analysis algorithms for the light scattering specialist
  • Expert advice report helps improve sample preparation or measurement process
