Particle size distribution inferred from small-angle X-ray scattering and transmission electron microscopy

Particle size distributions determined by small-angle X-ray scattering (SAX S) and transmission electron microscopy (TEM) are investigated for samples of interacting hard spheres, Polydispersity in the samples is determined fr om the SAXS data by fitting the Pored region to the form factor of a sphere of uniform electron density smeared by a Gaussian distribution of sphere d iameters. We find good agreement between SAXS-determined particle size dist ributions and those calculated from TEM image analysis.
