Abstract : Samples were analyzed using Photon Correlation Spectroscopy (PCS). The average diameter of the sample particles analyzed with this method ranged from 0.196 to 0.310 microns. Selected samples were also analyzed using Transmission Electron Microscopy (TEM). The data from these analyses were fit to a cumulative log normal distribution with mean diameters ranging from 0.160 to 0.217 and betas ranging from 0.61 to 0.77. Finally, results received from a commercial vendor (Brookhaven Instruments Incorporated) who analyzed two samples using PCS indicate a biomodal distribution with mean particle diameter ranging from 0.296 to 0.298 microns with beta ranging from 0.37 to 0.75. The mean diameter for this analysis ranged from 0.198 to 0.350 microns.
