The Particle Size Paradox

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.

Who Should Attend

This webinar will benefit beginners and professionals in research, development, processing or quality control who want to acquire a basic understanding of comprehensive material characterization or who want to refresh and expand existing knowledge. Furthermore, those who are looking for suggestions for further possible uses of physisorption, chemisorption, mercury porosimetry, particle size characterization and powder rheology as well as microreaction technology should attend this webinar.

What You Will Learn

  • Why different particle size technologies exist
  • How to understand particle size data from different techniques
  • Is more than one technique needed to completely characterize a material
