Quality control of fine powders

The new Camsizer XT – wide measurement range and variable dispersion methods

The quality control of fine powders in a size range from 1 µm to 3 mm can be substantially improved with the new Camsizer XT: More precise and faster analysis of particle size and particle shape helps to improve the product quality, reduce rejects and save costs. The design of the Camsizer XT is based on the well-proven optical particle measurement system Camsizer but is optimized for finer samples. Not only the improved optical resolution but also new options for material feeding allow for an extended application range. Fine particles tend to agglomerate which makes it difficult to record the properties of a single particle. Therefore, it is important to have various possibilities of feeding the sample to the analysis area to be able to find for each material the optimum between the desired dispersion of the agglomerates and the undesired destruction of the individual particle. The Camsizer XT offers three alternative dispersion methods: Pourable, not agglomerated particles are fed to the analysis area by a vibrating feeder.  With the dry powder feeder agglomerated particles can be accelerated and dispersed through a nozzle with adjustable overpressure. Finally, particles can be dispersed in liquids in the wet module, optionally with ultra sound. Thus it is possible to choose the optimum method for each sample type.
