  • Patent number: 6623697
    Abstract: Analysis device for analyzing samples, in particular of body liquids, with respect to components contained therein. It comprises a plurality of liquid handling (LH) stations. At at least a part of the LH stations there is a production of liquid waste whereby said LH-station form liquid waste sources. The liquid waste is evacuated, with at least one pump, from the liquid waste sources, with different proportions of air, via a liquid waste conducting system, into a liquid waste container. A substantial reduction of foam production is obtained by connecting at least two liquid waste sources to the liquid waste container via at least two liquid waste lines leading separately into the liquid waste container, whereas liquid waste sources with a higher average air proportion are connected to a first liquid waste line and liquid waste sources with a lower average air proportion are connected to a second liquid waste line.

  • Patent number: 6599473
    Abstract: A method for analyzing a liquid test sample by electrochemiluminescence. The method includes at least one specific biochemical binding reaction that leads to the formation of a complex which contains a chemiluminescence marker and the binding of the complex to a magnetic microparticle. Detection is carried out in a measuring cell having a working electrode in order to determine the concentration of the marked microparticle. The detection cycle includes a purification step, a conditioning step, a recovery step and a measuring step. A specified potential profile is applied to the working electrode during these steps. Between the conditioning step and the recovery step, an additional potential pulse with an oxidizing and/or a reducing potential is inserted into the voltage shape of the detection cycle in order to improve the deposit of the microparticle.
