Particle Size tutorial, overview of methods – Dispersion

These industries include pharmaceuticals, cements, ceramics, paints, emulsions, etc. In general, particle size analyzers can be roughly organized into three groups: 1) counters; 2) fractionation methods; 3) macroscopic fitting methods. Below we present links to several International Standards which provide descriptions of some of these methods.

Particle Size Analysis – an overview | ScienceDirect Topics

Particle size analysis is a complex procedure involving sampling, dispersion, and accurate use of instruments. Because any one of these operations can be inadequately performed, reference materials have been developed in recent times. These are distinguished by having the size distribution measured very carefully by a number of expert laboratories.
