    摘要: An electrokinetic pump achieves high and low flow rates without producing significant gaseous byproducts and without significant evolution of the pump fluid. A first feature of the pump is that the electrodes in the pump are capacitive with a capacitance of at least 10−4 Farads/cm2. A second feature of the pump is that it is configured to maximize the potential across the porous dielectric material. The pump can have either or both features.

    摘要: Electroosmotic flow systems containing two or more electroosmotic flow elements which meet at a junction, at least one of the electroosmotic flow elements having a substantial charge ratio. The electroosmotic flow elements have matching flux ratios. The electroosmotic flow elements may contain porous materials whose terminal portions are shaped to increase the surface area exposed to the fluid at the junction. Examples of such terminals are illustrated in the figure.

    摘要: A liquid sample is prepared at a preparation site and then processed, e.g. in an HPLC column. The sample is prepared and conveyed to the device at a flow rate which is substantially less than the flow rate through the device. The different flow rates are preferably provided by variable rate working fluid supplies which drive the sample from the preparation site and through the device.
