Abstract: An electrophoresis apparatus is generally disclosed for sequentially analyzing a single sample or multiple samples having one or more analytes in high or low concentrations. The apparatus comprises a relatively large-bore transport capillary which intersects with a plurality of small-bore separation capillaries and includes a valve system. Analyte concentrators, having antibody-specific (or related affinity) chemistries, are stationed at the respective intersections of the transport capillary and separation capillaries to bind one or more analytes of interest. The apparatus allows the performance of two or more dimensions for the optimal separation of analytes. The apparatus may also include a plurality of valves surrounding each of the analyte concentrators to localize each of the concentrators to improve the binding of one or more analytes of interest.

Abstract: Apparatus comprises an analyte concentrator (one or more) for insertion into a capillary tube and containing various structures for carrying chemical substances in the flow path for attraction or repulsion of samples passed through the capillary.

Abstract: The apparatus includes a capillary tube having input and output ends and having a detector coupled thereto. A rotatable table is provided at each end of the capillary tube and each table includes sample cups for containing samples to be analyzed, and, if desired, a medium to be introduced into the capillary for transporting a sample substance to be analyzed. An electrode is provided adjacent to each end of the capillary tube for applying electrical potential across the capillary tube to cause charged particles of a sample to flow through the capillary tube and past said detector which detects the components of the sample.Electronic means, including a computer, are provided for causing various portions of the apparatus to operate automatically when performing an analytical operation.
