Size by Dynamic Light Scattering (DLS) Study

Dynamic Light Scattering (DLS) is a type of spectroscopy that uses a laser beam to irradiate a sample containing particles in suspension resulting in light scattering. Rapid fluctuations in scattering intensity around a mean value at a certain angle occur because of particle diffusion and are dependent upon on particle size. The calculated correlation function yields a diffusion coefficient, for a given temperature and viscosity, that can be used to calculate particle size.
