Characterisation of Fine Particles with Dynamic Image Analysis

The quality control of fine powders in the size range from 1µm to 3mm can be substantially improved with Retsch Technology’s 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 optimised for fine samples in a size range from 1µm to 3mm. Fine particles tend to agglomerate which makes it difficult to record the properties of a single particle. Therefore, it is important to have different ways of feeding the sample to the analysis area in order to get the desired dispersion of the agglomerates without destroying the individual particle.

The CAMSIZER XT offers three alternative dispersion methods: dispersion by gravity of pourable, not agglomerated particles. Dispersion of agglomerated particles by air pressure, accelerating and dispersing the particles through a nozzle with adjustable overpressure. Finally, particles can be dispersed in liquids, optionally with ultra sound. Thus it is possible to choose the optimum method for each sample type.
