Capillary Zone Electrophoresis

Zone electrophoresis in open tubular capillaries is a useful approach to high-resolution separations of charged substances. Efficient heat transfer from small diameter capillaries permits application of unusually high voltages, which promote more effective separations and increase the speed of analyses. A sample injection technique and on-line zone detection create an instrumental format for zone electrophoresis. The basic theory, system parameters, and preliminary results are described.
