Abstract
The inversion of static light scattering measurements (SLS) for the evaluation of particle size distributions is reported. The performances of two inversiion methods, i.e., the maximum entropy method and a constrained regularization method (Contin), are illustrated with simulated data and experiments on samples with unimodal, bimodal, and trimodal distributions of spherical particles and on a sample with a broad size distribution. Some experimental results are compared to assessments by photon correlation spectroscopy (PCS) and electron microscopy (EM). It appears that a significantly better resolution in particle size is obtained by SLS than by PCS. However, for a sample with a broad distribution in particle sizes, not all details of the distribution observed by EM were resolved.
