Static light scattering is a technique in physical chemistry that measures the intensity of the scattered light to obtain the average molecular weight Mw of a macromolecule like a polymer or a protein in solution. Measurement of the scattering intensity at many angles allows calculation of the root mean square radius, also called the radius of gyration Rg. By measuring the scattering intensity for many samples of various concentrations, the second virial coefficient, A2, can be ca… WebWith the scattered light measurement principle, there are two options to choose from: With backward scattering, the light reflected from the particles is measured (2). In forward scattering, the radiation scattered by refraction (3) or diffraction (4) in the forward direction (5) of the incident light serves as the measurand.
