Ultrafiltration, the use of a semi-permeable membrane to facilitate the separation of molecules in solution, is a widely-used process. It is however far from fully understood in many respects. The relationship between the nominal molecular weight cut-off ascribed to a membrane by a manufacturer (90% of spherical, uncharged molecules of this weight should theoretically be retained) and its behaviour in actual use is not always predictable. Other physical and chemical properties of the filter may also be of importance. Ultrafiltration is the result of a variety of subtle interactions between various components. [Continues.]
