Prediction of Particle–Size Distributions from Spectrogoniophotometric Measurements

Abstract

The light-scattering properties of a colloidal suspension of particles serve as a basis for an empirical method to predict its particle-size distribution. Spectrogoniometric measurements on a wide variety of colloidal suspensions permit functional relationships to be established between these data and corresponding particle-size data from photomicrographic measurements; the predictability of the empirical functions appears to be excellent. As opposed to traditional photomicrographic techniques, the method described represents a straightforward, objective, and economical approach to particle-size determination. All computations, including plotting of the particle-size distributions, are performed by a computer program written for IBM System/360-65.
