Particle Shape Factors and Their Use in Image Analysis – Part 1: Theory

ABSTRACT Fine particles are often characterized by their particle size and distribution as determined by various analytical instruments. Particle shape may be just as important as particle size. Particle shape, however, is often ignored or disregarded. Image analysis

Surface Area

The Importance of Sample Preparation When Measuring Specific Surface Area

ABSTRACT Specific surface area is a fundamental measurement in the field of fine particle characterization. Specific surface area measurements have numerous pharmaceutical manufacturing and quality applications. Compliance professionals should have a general understanding of the principles, procedures, and
