Data analysis and distribution weighting: FAQ for DLS users

Dynamic Light Scattering (DLS) is a popular technique for obtaining size distributions of dispersible colloidal particles as well as other nanomaterials. As with all other light scattering based techniques, the intensity of scattered light is strongly skewed towards larger particles, something that must be considered when analyzing samples with two or more major constituents.
