Particle characterisation


 

The fully automated Sysmex FPIA-3000, from Malvern Instruments, delivers size and shape data by measuring thousands of particles in just minutes. For abrasives there is a direct link
between particle shape and product efficacy, this information can help in the manufacture of improved materials. “Demand for increased abrasion accuracy has driven down the grain size of abrasives to the detriment of polishing efficiency,” said Ulf Willen, product manager for analytical imaging at Malvern Instruments. “Research has shown that there is a direct correlation
between circularity, a shape parameter, and polishing efficiency, so controlling shape is a way of offsetting this problem. We’re finding that manufacturers are using the Sysmex FPIA-3000 to fine tune manufacturing, and also for QC, to
make products that perform better and command a higher price.”
