WebDynamic light scattering enables the analysis of particles in a size range from 0.3 nm to 10000 nm. While Laser Diffraction (LD) often reaches its limits for particles smaller than 100 nm due to the weak signal and the low angular variance in scattering signal, this is where the strength of dynamic light scattering lies. http://www.scidict.org/items/dynamic%20light%20scattering.html
