The Malvern Zetasizer series measures particle and molecule size from below a nanometer to several microns using dynamic light scattering, zeta potential and electrophoretic mobility using electrophoretic light scattering, and molecular weight using static light scattering. In addition the system can be connected to a GPC / SEC system to use as a chromatography detector. The system is available in a range of variants that allows you to select the best system for your application and budget, and the philosophy of the design is to ensure exceptional ease of use and give confidence in the results without compromising performance.

In particular, this article demonstrates the correlation between molecular changes (Raman Spectroscopy) and microstructural evolution of rheological properties (DLS, DLS-optical microrheology) for the first time for surfactant-based wormlike micellar...
The measurement of the zeta potential of non-aqueous suspensions is challenging as the electrophoretic mobility of the particles is very small. Here we describe how the Zetasizer Nano in combination with a universal dip cell accessory gives excellent...
This note discusses how DLS-based optical microrheology can be used to determine the rheological behavior of polymer solutions and the impact of tracer particle chemistry on the measured microrheological response.

This presentation discusses the importance of particle size, zeta potential and rheology for a functional suspension, and demonstrates how these properties can be manipulated to induce dispersion stability.
As part of the multi-disciplinary lab at QMUL, materials and biomaterials research groups throughout the university, from engineers and chemists through to biologists and physicists, are benefiting from access to analysis using the Zetasizer Nano.
