Webinar: The Particle Size Paradox: Is there a single best particle size technique?

Veranstaltungsort: Online
Particle size is an important piece of information for research and development, quality control, and quality assurance as well as understanding the small physical details in a milling or powder compaction process. These details can contribute to potential desired and undesired products. With recent technological advances, particles are now measured using various analytical techniques and instrumentation.

Different analytical techniques seldom provide the same value for particle size. The “paradox” of particle sizing is that all the different values are the correct value. The six analytical particle sizing instrument techniques discussed and compared include dynamic image analysis, sedimentation, static light-scattering (or laser diffraction), electric sensing zone, air permeability, and dynamic light scattering. The result of the comparison is that particle size data is specific to the analytical technique used to collect that size data and particle shape is an important characteristic to consider.
