- the size of the particles may be the median value d50 determined by transmission electron microscopy (TEM): by observing several SEM images, it is possible to obtain a number distribution of the diameters of the particles.
- the distribution therefore represents the number of particles distributed by classes, the class width being adapted to the size of the particles and taking into account the maximum size.
- the number of classes is generally between 10 and 20.
- the number of particles in each class is the basic data to represent the (cumulative) number distribution.
