Malvern Instruments recently announced an ‘early access program’ that is designed to introduce the benefits of combining automated particle size/shape analysis on the Morphologi G3 system with chemical identification provided by Raman spectroscopy, in the form of the new Morphologi G3-ID.

The Morphologi G3 is a fully automated, proven system that uses microscopy-based image analysis for the characterisation of particle size and shape. The addition of a Raman microprobe enables chemical as well as physical characterisation of particulates. This can be critical in troubleshooting out-of-specification products, for instance, where it is important to know whether outliers are misshapen particles of the correct material or foreign contaminants.

Able to characterise particles between 0.5µm and 10mm in size, the Morphologi G3-ID is capable of determining chemical composition, particle distribution in a mix of individual components, and foreign particle contaminants. It can also ascertain whether a particle contains single or multiple chemical components.
