The determination of the molecular weight distribution of polymers can be performed by a variety of methods, both absolute and relative. The absolute methods (fractionation, light scattering, osmometry) are used only when strictly necessary, due to lenghty and/or experimentally difficult procedures; the relative methods (GPC, ultracentrifugation, intrinsic viscosity) need a calibration by absolute methods. All of these methods utilize the polymer dissolved in solvents.
