Diffusion or perfusion — this is no longer the question for electroosmotic flow (EOF) through capillaries with fixed beds. The intraparticle EOF in capillary electrochromatography has been shown by using special NMR techniques and forms the basis for a further improvement in separation efficiency, mass sensitivity, and analysis speed. Electroosmotic perfusion phenomena in porous materials also play an important role in other areas, such as in the dewatering of waste sludge and the removal of contaminants from soil.
