Abstract
A system for controlling the bulk flow rate in capillary electrophoresis employs pressure to increase velocity without unacceptably increasing plate height. Thus, the system controls bulk flow over a range of velocities, independent of the chemistry of the system. Additionally, the use of pressure under certain conditions may decrease plate height and improve resolution.
