Diffractometers for Characterizing Particle Size Distributions of Fineparticles

Percent Larger Than or Equal To Stated Size 

Diffractometer Resistazone Mean (microns) 20.19 20.11 Spherical Latex Median (microns) 20.29 20.27 Mode (microns) 20.56 20.44 

Depending on the system used, the diffractometer can size fineparticles over a wide range. The literature of specific manufacturers should be consulted for their stated range of measurements.
