ABSTRACT
In this chapter we present some general stereological principles required for making estimates of mean particle ‘size’ for a population of particles. In common with the techniques described throughout the remainder of the book these methods do not rely upon unfounded ‘assumptions’ about particle shape (e.g. that the particles are ellipsoidal, spherical, etc.). Many of the themes already encountered in the preceding chapters, particularly the idea of using geometrical probes, will be called upon here to sample particles.
