  • Patent number: 7329388
    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.

  • Patent number: 6743356
    Abstract: A high throughput high performance chromatography system operating at a high mixing pressure including a plurality of pressurized solvent reservoirs, e.g. pumps, each maintaining an associated solvent at a substantially constant pressure. A plurality of flow control valves are connected downstream or upstream of the reservoirs for controlling the flow rate of the solvent into the respective columns. The number of reservoirs equals the number of solvents. Accordingly, the system reduces the number of pumps required thereby saving money and space. Furthermore, the system increases sample throughput, accelerates method development and minimizes organic waste.

  • Patent number: 5045172
    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.
