Laser Laboratories Analyse Size Standards
Feb 13 2006
Under the auspices of the Laser Diffraction Proficiency Testing Scheme (LDPTS) more than 60 laboratories analysed four glass microsphere particle size standards covering the size range from 1 - 350 microns. While a number of testing laboratories produced results that were in excellent agreement with the certified standards, some showed significant deviations.
This work highlights the need for reference standards in combination with prescriptive methods of analysis. It also explains why there has been a significant surge in the use of such materials in laboratories performing precision particle size analysis.
