The counting of particles is likewise a cornerstone of biologic, chemical, medical and physical analysis methods. Generally, there is a differentiation between a particle-counter and a single-particle-counter. Particle counts are of utmost importance in the manufacturing process of pharmaceutical products and the inspection of cleanness of industrial processes.
Characterization of particle dimensions of disperse systems, or just simple determination of the particle size, is of great interest in the industrial, biological and pharmaceutical sector. Countless properties are tied to the size of a particle, like dispersion and flow behavior, stability of particle ensembles and agglomeration attributes.
