Particle Dispersion for Size Analysis
Jorie Kassel, Fine Particle Analyst II
ABSTRACT
Particle size analysis is a vital analytical tool in the pharmaceutical industry. The results can be used to meet safety and quality specifications and provide information for product development
and manufacturing. While particle size analysis can provide great insight, it can be nearly meaningless if it is obtained improperly. Errors observed in the generation of particle size data occur due to the selection of a technique inappropriate to the material type or through the use of poor sampling and dispersion techniques (i.e., sample preparation). In many cases, the end application in which the particle size will be used is not properly considered, thus the amount of dispersion needed is inadequate or overcompensated.
