Malvern provides particle option

Published: 3-Jan-2006

Malvern Instruments displayed its Zetasizer Nano particle characterisation system - a combined static, dynamic and electrophoretic light scattering system ideally suited for the characterisation of protein samples', and the first commercial instrument to include hardware and software for combined dynamic, static and electrophoretic light scattering measurements.


Malvern Instruments displayed its Zetasizer Nano particle characterisation system - a combined static, dynamic and electrophoretic light scattering system ideally suited for the characterisation of protein samples', and the first commercial instrument to include hardware and software for combined dynamic, static and electrophoretic light scattering measurements.

The company designed a system to meet the low concentration and sample volume requirements associated with pharmaceutical and biomolecular applications by integrating a 'backscatter optical system' and 'novel cell chamber'.

Able to measure particle size, zeta potential and molecular weight in nano-sized particles and molecules in solution, it has been used in studies comparing two forms of a therapeutic antibody, and for the characterisation of immunoglobulins, examining the effects of different storage conditions on the size and quality of an antibody preparation.
