The term Morphology refers to the study of structure and form of organisms. Dividing particles in various classes and explaining their properties by fitting different parameters is the goal of morphology.
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.
A system is considered stable, if it does not change over time under the influence of no or just small external forces. Having little variance is crucial to ensure high quality and especially final products need to be stable for extended periods.
