Cross-analytical characterization of particles and dispersions at POWTECH

If dispersion stability, particle size & shape or flowabality of powders matter, visit POWTECH 2010 - Hall 6 Stand 6-114
(PresseBox) (Berlin, ) L.U.M. GmbH, Berlin, welcomes all visitors to present innovations in the fields of dispersion analysis and particle characterization. During POWTECH besides L.U.M. products also new instruments for particle shape analysis and flowability of powders are presented. Nonspherical reference particles complete the presented highlights. All visitors are provided with a comprehensive insight into the fascinating world of dispersion and particle characterization.

The new Demixing Tester LUMiCheck® (L.U.M. GmbH) is your first step in dispersion analysis. This instrument is especially designed for the quality assurance lab. It is used for the uncomplicated, comparative stability analysis and particle characterization of dispersions in their original state (without sample preparation or dilution). The fast quantitative comparison of different samples and the qualitative characterization of demixing behaviour, flocculation, sediment formation and stability make LUMiCheck the instrument of choice for the measurement of beverages and food, construction material, fuel and lubricants, and generally speaking for a large variety of emulsions and suspensions.

The Dispersion Analyzer LUMiSizer® made by L.U.M. GmbH is the complete dispersion lab in just one instrument. The LUMiSizer® simultaneously determines the demixing of 12 different dispersions at original concentration, based on the patented STEP®-Technology. Due to the acceleration of the demixing in the LUMiSizer up to a factor of 2300, information about e.g. colloidal stability, surfactant influence, particle size, agglomeration and flocculation of dispersions is obtained in drastically shortened time. The variation of the centrifugal field provides in addition, comparable to a falling sphere viscometer, first information about the rheological behaviour of a dispersion.

The fast characterization of any demixing and consolidation, the calculation of the velocity distribution as well as of the particle size distribution make the LUMiSizer the instrument of choice for research and development, for process optimization and quality control in nanotechnology and in e.g. food, ceramic, cosmetic, paint and chemical industries.

For rapidly demixing systems and for the analytical longterm monitoring of emulsions and suspensions L.U.M. GmbH presents the product line LUMiReader®, adding objectivity to your view on stability and shelflife.

PS Prozesstechnik GmbH, Switzerland, is specialized in the development and sales of instruments for online and offline characterization of particles in suspensions, powders, granules and emulsions. XPT Particle Measurement Instruments with dynamic image analysis for powders and suspensions are exhibited, having particle size, number and shape in focus. The flowability of powders can be measured using ShearScan and Revolution Powder Analyzer. PS Prozesstechnik additionally develops membrane processes for concentration and purification of your product.

Powdershape and Fibreshape (Innovative Sinter Technologien AG, Switzerland) is an image analysis based system that enables to characterize statistically size, shape and optical properties of particles and fibres. The measurement size range is from 2 ?m to 20 cm object length. IST AG moreover provides solutions for quality assurance of material and their preproducts using quantitative image analysis.

The worldwide novelty Isomorphic nonspherical reference particles (Dr. Lerche KG, Germany), complete the presented POWTECH highlights. These references particles (dry or in suspension) are used for the validation and optimization of particle shape analyzers during their development, production and at final customer site. Ready to use for measurement, the reference particles are available in various shapes and aspect ratios.

Representatives from all companies welcome you during POWTECH 2010 in Hall 6 at LUM-Stand 6-114.
