The Particle Size Paradox

June 9, 2020

Overview

Is there a single best particle size technique? Particle size provides important 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. 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.

Listen to Jack Saad, Associate Scientist and Global Technical Training & Support Manager with Micromeritics, when he compares the six analytical particle sizing instrument techniques:

  • Dynamic image analysis
  • Sedimentation
  • Static light-scattering (or laser diffraction)
  • Electric sensing zone
  • Air permeability
  • Dynamic light scattering
