Accusizer

Common measurement methods consider a large number of particles and determine the mean value using mathematical functions. However, as soon as particles of a similar size are to be distinguished, these methods no longer work.

In many applications, like in polishing agents or in pharmaceutical products, even a few larger particles are harmful. A large particle in a polishing compound can damage the surface of the component. A particle that is too large, administered intravenously, can cause an embolism in a patient's bloodstream.

Such particles can be quantitatively detected with the AccuSizer from Entegris (formerly PSS) by absorbance measurement (between 150nm and 1500µm).

For particles down to 0.5nm, Entegris offers a measuring device that can measure in a size range from 0.5nm to 5µm.

The zeta potential is important for the production of emulsions. While the zeta potential measurement in other systems involves a great deal of effort, the Nicomp can be used to determine the zeta potential within a few seconds in addition to the particle size.
