How to analyze Dynamic Light Scattering (DLS) results

WebThe intensity of the scattered light is proportional to the particle size, and the angle of the scattered light is proportional to the particle’s diffusion coefficient. DLS is a non-invasive, real-time technique that can be used to study a variety of particle systems. Webthe intensity of the scattered light is directly related to the molecular weight of the molecules: higher molecular weight molecules scatter more light. Secondly, the scat-tered light’s intensity is not identical in all directions, and this dissymmetric scattering pattern is related to the size and shape of the molecules.
