Abstract
The present disclosure is directed to a method of particle size determination for particles suspended within a light-transmissive medium. The method includes directing a monochromatic light source into the medium and collecting from the medium a Raman-scattered light spectrum. The method includes analyzing the Raman spectrum to determine an amount of Tyndall scattering of the Raman spectrum caused by particles within the medium, and thus determine the size and the number of particles mediating the Tyndall scattering.
