RODOS is the original by the inventor of dry dispersion. With this breakthrough innovation, Sympatec has opened up dry applications to particle measurement technology – as early as 1982.
Since then, it has been possible to dry measure powders, fibres and granules appropriate to the product, with both laser diffraction and dynamic image analysis. No other method of dispersing is anywhere near as powerful or achieves such an efficient as well as gentle dispersion from the submicron to millimetre range.
This standard operating procedure provides Missouri State University (MSU) Ozarks Environmental and Water Resources Institute (OEWRI) laboratory personnel procedures for the operation of the LS 13 320 Laser Diffraction Particle Size Analyzer. 5 Summary of method Sediment samples are collected and stored in ambient conditions in Temple Hall. Particle Analytical can determine these refractive index parameters. The laser diffraction instrument applied by Particle Analytical (Malvern Mastersizer 2000 and 3000) has a flow-through cell for dispersion of particles in liquid media or a dry dispenser for dispersion of particles in air.
Inspired by capsule technology, the coffee industry is constantly bringing new types of coffee onto the market that continue to stimulate consumption. This increases the requirements for quality control, particularly with respect to the particle size distribution of coffee powder. Another challenge is the strong internationalisation of coffee producers, which makes comparability of analyses at different locations necessary. Industrial grinding of coffee and frequent changes in variety require a consistent, partially automated control of the particle size distribution to ensure consistent product quality.
