Sedimentation Rate an overview ScienceDirect Topics

As we will outline below, sedimentation velocity is based upon a rigorous hydrodynamic and thermodynamic theory. Sedimentation velocity allows the determination of purity or homogeneity of a macromolecular species (see the chapter by Arthur, Kendrick, & Gabrielson, 2015 in this volume). If there are contaminants or aggregates, these can often be quantified by velocity methods down to 0.1–1%.
