We propose a method for estimating the particle size distribution (PSD) of a latex with particle diameters in the sub-micrometer range, from combined elastic light scattering (ELS) and dynamic light scattering (DLS) measurements. As light scattering measurements are recognized to have a low information content on the unknown PSD, we propose a novel method that combines both measurements, to increase information content and contribute to improve the quality of the PSD estimate.
