ABSTRACT
The major advantage that microscopic techniques possess over most other methods of size analysis is that the particle profile itself is measured, rather than some property which is dependent on particle size. Since the particles are visible, the operator can assess easily whether or not they are properly dispersed, their shape is visible, and an intuitive feeling for the nature of the material is obtained. Most experienced particle size analysts would examine an unfamiliar sample by microscopy in order to assess its general nature, shape, and cohesiveness, even without making any accurate measurements, prior to using one of the methods described in earlier chapters.
