Malvern Zetasizer Advance particle measurement system

Saturday, 01 August, 2020 | Supplied by: ATA Scientific Pty Ltd


The Malvern Zetasizer Advance has been designed to offer faster, more intelligent particle size analysis. The Malvern Zetasizer range of dynamic light scattering (DLS) instruments can measure particle and molecular size from less than a nanometre to several microns. The Zetasizer Pro and Zetasizer Ultra add ease and performance to the Zetasizer Nano range, offering updated measurement features, hardware capabilities and software intelligence that empower groundbreaking research. Now, Malvern Panalytical has expanded the range to include the Zetasizer Advance.

The latest family of dynamic light scattering (DLS) instruments has been designed to build and improve on the technologies first seen in the Zetasizer Nano, making it simpler, more versatile and more powerful. Combining DLS and electrophoretic light scattering (ELS) with non-invasive backscatter (NIBS) technology, the product is able to measure particle and molecular size, molecular weight and zeta potential across a wide range of concentrations.

Recent updates introduced into the Zetasizer Pro and Ultra systems, such as multi-angle dynamic light scattering (MADLS) and adaptive correlation, have enabled higher resolution data and an approach to data acquisition that separates the sample signal from that of external noise (such as from dust or other contaminants). This enables the user to obtain reproducible particle size data quickly and with minimal sample preparation.

ZS Xplorer software offers intuitive, guided workflows that make setting up a method and performing a measurement easy and straightforward. Using an artificial intelligence (AI)-led approach to data quality assessment, it brings attention to any potential measurement issues and provides guidance on how to improve them.

Overall, the systems provide a comprehensive analysis of users’ materials for a wide range of applications. Through the combination of novel measurement capabilities with advanced data analysis, users can characterise the size and surface charge of colloids and nanoparticles; screen protein formulations for colloidal stability and the presence of aggregates; and assess the shelf life and stability of complex formulations.
