Electrophoretic separating device and electrophoretic separating method
First Claim
1. An electrophoretic separating device comprising a channel which is provided with inlet and outlet openings, for example for a carrier medium, and which has at least one feed opening for a sample to be investigated, and having electrodes in the region of the inlet and outlet openings, which electrodes can be connected to a voltage source in such a manner than an electric field can be established along the channel, wherein the channel is divided into n channel sections and has, in addition to the feed opening for the sample, 2n inlet and outlet openings that are arranged in the region of connection between the channel sections, and wherein the channel is constructed in the form of an n-sided closed loop figure, the sides of which are formed by the channel sections.

Abstract
In an electrophoretic separating device, a channel defining a separating path is constructed in the form of a closed loop. A sample to be separated is introduced via a feed opening into an electrolytic carrier medium that is moved with the aid of an electric field through the channel, which is provided in the region of its ends with inlet and outlet openings for the carrier medium, and is separated into individual components by the electric field. The electric field is generated in the channel by connecting electrodes in the region of the inlet and outlet openings to different potentials of a voltage source. The procedure for carrying out the method according to the invention is distinguished especially by the fact that the carrier medium and the sample are moved along the substantially closed separating path formed by the channel which is constructed in the form of a closed loop.
