Abstract

A method is proposed for measuring the size of particles in a dynamic light scattering analyzer along with a determination of their number density in suspension. It is shown that this method can be used to measure the parameters of various nanoparticles, including nonspherical ones. An experimental prototype of a dynamic light scattering analyzer for measuring the number density of nanoparticles along with their sizes is described.
