NettetThe intensity-weighted distribution is specific to the dynamic light scattering (DLS) technique. In that case, the results are expressed as a measure of the intensity fluctuations of the light scattered by the particle. Nettetcontinuous differential number-weighted distri-bution into a continuous differential volume-weighted distribution, multiply by D 3. The end result is a continuous volume-weighted differen-tial distribution. Of course the initial numerical values will not be normalized, but that is easy to remedy.
