Abstract

At present, the methods of optical and electron microscopy, sedimentation, measuring of light scattering indicatrix, dynamic light scattering (DLS), etc., are used to determine the sizes of micron and submicron particles [1-3]. All aforementioned methods have their advantages and disadvantages. This work deals with the study of the potentialities of dynamic light scattering method for measuring the sizes of colloidal particles in samples characterized by wide distributions and consisting of several narrow-disperse components (fractions). An attempt was made to analyze the errors encountered in such measurements.
