Some misconceptions about comminution and particle size Available to Purchase

Excellent though they are for quality control, instruments which measure particle size by non‐optical means, tend to pass over features in powders and dispersions which can throw light on production problems or in product formulation. In effect, this is a plea for chemists to recruit optical methods in the study of powders, dry or wetted, alongside the indirect, instrumental methods which, it must be granted, have revolutionized quality control, and in some instances, research.
