In any form of training course (specifically sales and management) attendees usually come away with some form of phraseology or aide-memoire in the form of a three- or more-letter acronym (TLA) in order to reinforce a particular point or strategy. One classic example is SWOT (Strengths, Weaknesses, Opportunities, Threats) in the evaluation of virtually anything. Particle size analysis (PSA) is not immune to the TLA. In this talk, I will deal with the 3 C’s, 3 M’s, 3 R’s, 3 S’s, and the 4Q’s that allow particle sizing issues to be defined and diagnosed in a scientific and logical manner. 

We will include:

  • 3 C’s – Concentration, contamination, cleanliness
  • 3M’s – Material, method, machine
  • 3R’s – Repeatability, reproducibility, robustness
  • 3S’s – small, sensible, systematic (robustness parameters)
  • 4Q’s – 4 questions that need to be answered before the analysis
