    摘要： A chip for performing an electrophoretic separation of micromolecular or macromolecular structures in two dimensions comprises a base substrate comprising a main surface. A channel is formed in the main surface of said base substrate in a first direction, wherein a first voltage is applicable across the channel in order to allow a separation of micromolecular structures or macromolecular structures in the first direction on the basis of a first separation mechanism. In addition, a two-dimensional separation matrix is formed in the main surface of the base substrate, wherein the separation matrix comprises a shallow recess and an array of stand-alone posts arranged in the recess. The recess extends perpendicular from the channel in a second direction, wherein a second voltage is applicable across the separation matrix in order to allow a separation of the structures on the basis of a second separation mechanism.

    摘要： A miniaturized column analytical apparatus having a miniaturized column device containing a body with an elongate separation compartment is provided. Two or more sets of spaced apart antennas are positioned along the elongate separation compartment. The elongate separation compartment has first and second opposing sides along its elongate dimension. Each set of antenna contains a plurality of antennas. One antenna from each set is associated with at least one antenna from each of the other sets to form repeating sequences of antennas along the separation compartment on the opposing sides of the separation compartment. Each set of the antennas is associated with a different oscillating electrical potential to provide a plurality of oscillating electric fields along the elongate separation compartment to draw a target substance along the elongate separation compartment toward an exit end of the separation compartment. The detector can detect a target substance passing out of the elongate separation compartment.
