A novel procedure for the treatment of sedimentation velocity data by the method of moments is proposed for determination of polydispersity indices, such as M,JM,, etc. This method is based on linear approximations and enables the reliable exclusion of diffusion and concentration effects. It is particularly effective when applied to polymer solutions with strong intermolecular interactions and noticeable diffusion mobility of the macromolecules.
