<p>A method is disclosed for effecting the concentration of a polar analyte in an alternating electric field. In the method, a relative translation of the polar analyte and an alternating electric field along a translation path is effected. A portion of the polar analyte is then trapped and concentrated in a concentration zone formed by the intersection of the translation path and the alternating electric field. Also disclosed are various devices for carrying out the foregoing method.</p> |
