摘要
Devices are provided for separating and focusing charged analytes, comprising a separation chamber and two or more electrodes, for example, an electrode array. A membrane separates the separation chamber and the electrodes. The separation chamber of the device is configured, that is, the separation chamber has a shaped geometry, which serves to induce a gradient in an electric field generated by the electrodes in the electrode chamber. Optionally, molecular sieve is included in the separation chamber that is operative to shift the location at which a stationary focused band of a charged analyte forms under a given set of focusing process parameters. Methods are provided for separating and focusing charged analytes comprising introducing a first fluid comprising at least one charged analyte into the separation chamber of a device as just described, applying an electric field gradient to the charged analyte to focus the charged analyte in the electric field gradient.
