To simplify, from the bigger particle gives the stronger scattering and the smaller particle gives weaker scattering. As a principle, molecular weight is calculated from absolute value of scattered light obtained by irradiated light into colloidal particle. Static Light Scattering Method is renowned as the convenient method to know absolute molecular weight. Molecular Weight: Static Light Scattering Method
