Theoretical Investigations on the Light Scattering of Colloidal Spheres. XII. The Determination of Size Distribution Curves from Turbidity Spectra

Abstract

The theory of a method is outlined which gives size distribution curves in heterodisperse systems of non‐absorbing colloidal and small microscopic spheres from measurements of turbidity spectra. The assumption is made that the distribution follows a function previously given which closely approximates that commonly found in emulsions. All the numerical data necessary for practical application of the method are provided for the relative refractive indices m=1.05 (0.05) 1.30. They were obtained from the Mie theory. The method may be used independently, but is particularly useful in conjunction with an alternate method described in a previous publication (XI).
