Abstract:
New equations for static light scattering of dilute binary solutions allow molar mass determination of macromolecules from measurements of scattered intensity ratios between solution and solvent (Ir). In contrast to the standard Carr–Zimm equations, they do not rely on the experimental absolute value of the Rayleigh ratio of a reference liquid. The picture shows a typical plot for the surfactant BRIJ72 in CH2Cl2 (MSupplier=0.359 kg mol?1).
