New Wet Cell for Malvern's Morphologi G3 Extends Particle Size and Shape Applications


Morphologi G3 now offers wet and dry particle characterization

7 May 2009: Malvern, UK: The introduction of a new large volume wet cell extends the range of sample types that can be analyzed with the award-winning Morphologi G3 automated particle characterization 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 2 ml 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 analyzing 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.

About Malvern Instruments

Malvern Instruments provides a range of complementary materials characterization tools that deliver inter-related measurements reflecting the complexities of particulates and disperse systems, nanomaterials and macromolecules. Analytical instruments from Malvern are used in the characterization of a wide variety of materials, from industrial bulk powders to nanomaterials and delicate macromolecules. A broad portfolio of innovative technologies is combined with intelligent, user-friendly software. These systems deliver industrially relevant data enabling our customers to make the connection between micro (such as particle size) and macro (bulk) material properties (rheology) and chemical composition (chemical imaging).

Particle size, particle shape, zeta potential, molecular weight, chemical composition and rheological properties measurements are now joined by advanced chromatography solutions (GPC/SEC), extending Malvern's technologies for protein molecular weight, size and aggregation measurements, and synthetic polymer molecular weight and distribution. The company's laboratory, at-line, on-line and in-line solutions are proven in sectors as diverse as cement production and pharmaceutical drug discovery.

Headquartered in Malvern, UK, Malvern Instruments has subsidiary organizations in all major European markets, North America, China, Korea and Japan, a joint venture in India, a global distributor network and applications laboratories around the world. www.malvern.com
