Some published articles purport to demonstrate the difficulties and problems of the laser diffraction technique without mentioning that these apparent problems are inherent in all particle-sizing techniques. This article discusses some of the advantages of using laser diffraction for particle sizing-including repeatability, ease of verification, and speed of measurement-and why it has become the preferred technique in a range of industries.
