CAMSIZER® XT
The quality control of fine powders 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 labor costs, energy and raw materials.
The design of the CAMSIZER XT is based on the well-proven optical particle measurement system Camsizer but is optimized for finer samples (from 1 µm to 3 mm). 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 the flexible X-Change system: from the X-Fall module (free fall mode), which is the most gentle method for the material, to the X-Jet module with adjustable pressure and variable nozzle geometry and, additionally, the X-Flow module in which particles are dispersed in liquids, optionally by an ultrasonic probe.

作用原理
The CAMSIZER XT uses the principle of digital image processing. The patented principle is fairly simple: Dispersed particles pass in front of two bright, pulsed LED light sources. The shadows of the particles are captured with two digital cameras. One camera is optimized to analyse the small particles with high resolution, the other camera for the detection of the big particles with a good statistic, that means large field of view. Each camera is illuminated by one LED with optimized brightness, pulse length and field of view. A user-friendly software analyzes the size and shape of each particle, and finally calculates the respective distribution curves in realtime.

Sample preparation errors can no longer be corrected even by the most up-to-date analytical instruments. This is why Retsch Technology offers a range of sample dividers for obtaining representative part-samples.
