Measuring particle shape and size with dynamic image analysis

摘要

The new Analysette 28 ImageSizer (Fig. 1) by Fritsch is the ideal instrument for analysis of particle shape and size of dry, free-flowing powders and bulk solids in a measuring range from 20 μm to 20 mm - individually adaptable. Via optical analysis of particle shape and particle size, damaged particles, contaminates, agglomerates or oversized- or undersized-particles are recognized accurately and quickly and can be viewed as single images via the high-performance camera with telecentric lenses (Fig. 2). At the same time, the instrument offers a fast and efficient particle size measurement. The measuring time, depending on the sample quantity, is below 5 min. and the result is available immediately. Thus, the device is the perfect measuring instrument for easy quality control, as well as for research and for laboratory tasks - and it is the fast alternative to sieving.
