New Zetasizer Nano ZSP offers emerging rheology technique for weakly structured fluids
With the recent launch of the new top of the range Zetasizer Nano ZSP system, Malvern Instruments has added dynamic light scattering (DLS) Microrheology to its portfolio of materials characterization techniques. To introduce this powerful technique, the company has published an in-depth paper that explains the background to microrheology, and how it can be used to investigate the rheological properties of even the most weakly structured fluids, using sample volumes on the microliter scale. ‘An Introduction to DLS Microrheology’ includes data for protein (bovine serum albumin (BSA)) and polyethylene oxide (PEO) solutions that illustrate the significance and usefulness of the method. It is freely available from the Malvern website.
