Particle Size Analysis

Particle size analysis is used to characterize the size distribution of particles in a given sample. Particle Size analysis can be applied to solid materials, suspensions, emulsions, and even aerosols. There are many different methods employed to measure particle size. At Moore Analytical we use laser diffraction with both a liquid and dry sampling method to provide the best measurement quality for your samples.


The Microtrac S3500 is the first particle size analyzer that uses three precisely placed red laser diodes to accurately characterize particles like never before. The patented Tri-Laser System provides accurate, reliable, and repeatable particle size analysis for a diverse range of applications by utilizing the proven theory of Mie compensation for spherical particles and the proprietary principle of Modified Mie calculations for non-spherical particles.


The S3500 measures particle size from 0.02 to 2,800 μm.


Particle size analysis is a very important test and is used for quality control in many different industries. In just about every industry where milling or grinding is used, particle size is a critical factor in determining the efficiency of manufacturing processes and performance of the final product. Some industries and product types where particle sizing is used includes:

  • Pharmaceuticals
  • Building materials
  • Paints and coatings
  • Pigments
  • Abrasives/Blast Media
  • Metal Powders
  • Filtered Solids
  • Wear Debris
  • Catalyst
  • Drilling Mud
  • Geology
