Extended Particle Size and Shape Analysis Applications

The introduction of a new large volume wet cell extends the range of sample types that can be analysed with the award-winning Morphologi G3 automated particle characterisation system from Malvern Instruments.
Equipped with the new wet cell accessory the Morphologi G3 measures size, shape and intensity of particles for a wide range of wet dispersions and emulsions. This adds to the system’s existing capabilities, which
include the analysis of dry powders and characterization of foreign particulate material on filters.

Liquid suspensions often present major challenges for analysis using conventional microscopy instrumentation since it is possible to measure only limited sample volumes under a cover slip. Obtaining statistically relevant quantitative data is therefore problematic.

With its 2ml interior volume and large scan area, the new wet cell overcomes these limitations. Furthermore it is magnetically clamped together to prevent sample evaporation during analysis and to allow easy cleaning between measurements. The Morphologi G3 delivers high quality imaging and statistically significant particle size and shape information in a single measurement, with minimal user intervention. With the addition of the new wet cell it becomes an ideal solution for applications as diverse as analysing the packing characteristics of gypsum slurries and assessing the mouth feel of chocolate.

With the Morphologi G3, for every particle measured there is a choice of 20 different parameters to describe size and shape. Software tools compare and cluster data to find differences and similarities between multiple measurements. With just a few clicks of the mouse, data is transformed into useful information, allowing the user to make decisions quickly and with confidence.
