Particle Sizing An Introduction Silver Colloids
A true weight distribution is not produced as the method relies on measuring the second smallest dimension of the particle. This can produce strange results with rodlike materials such paracetamol. It is a lowresolution method and usually only four to five size classes are provided.

Determination of particle size distribution and analysis ...
Median values (Md) are defined as the value where half of the population resides above this point, and half resides below this point. For particle size distribution the median is called the D50. The D50 is the size in microns that splits the distribution with half above and half below this diameter.
