Malvern’ Zetasizer series measures particle and molecule size from below a nanometer to several microns using dynamic light scattering, zeta potential and electrophoretic mobility.

Electrophoretic mobility uses electrophoretic light scattering and molecular weight via static light scattering.

The system can be connected to a GPC / SEC system as a chromatography detector.

In addition, the system is available in a range of variants that allows the selection of the best system for a specific application and budget.

The design ensures ease of use and confidence in results without compromising performance.

The Zetasizer Nano range is the world’s most widely used systems for nanoparticle, colloid and protein size, zeta potential measurements and molecular characterisation.

The Zetasizer Helix characterises secondary and tertiary structure to develop mechanistic insight into oligomerisation and aggregation.

The device measures protein aggregation, zeta potential, protein mobility, molecular size and weight, and has spectral performance of 150cm-¹ to 1850cm-¹.

In addition, Zetasizer Helix uses raman spectroscopy, dynamic light scattering, static light scattering, and electrophoretic light scattering technology.
