  • Patent number: 8445290
    Abstract: A biosensor system determines analyte concentration from an output signal generated by an oxidation/reduction reaction of the analyte. The biosensor system adjusts a correlation for determining analyte concentrations from output signals at one temperature to determining analyte concentrations from output signals at other temperatures. The temperature-adjusted correlation between analyte concentrations and output signals at a reference temperature may be used to determine analyte concentrations from output signals at a sample temperature.

  • Publication number: 20130121883
    Abstract: An automatic chemical analyzer in which a reaction solution is stirred by air ejected from an air ejection hole placed above a reaction container. The reaction region can be washed and cleaned sufficiently without causing damage, such as exfoliation of a coating reagent. A reaction container disk is provided with a pore and a pressure detector connected with the pore. Before and after the stirring operation, the ejection hole (nozzle) ejecting air is moved and the output value of the pressure detector is compared with a previously measured normal value. With a discharge pipe and a suction pipe inserted to the opening of the reaction container to be close to both ends of the opening and the side wall of the container, the reaction region at the bottom of the container is washed by continuous discharge and suction of cleaning fluid.

  • Patent number: 8389288
    Abstract: The invention relates to a device for the carrying out of chemical or biological reactions with a reaction vessel receiving element for receiving a microtiter plate with several reaction vessels, wherein the reaction vessel receiving element has several recesses arranged in a regular pattern to receive the respective reaction vessels, a heating device for heating the reaction vessel receiving element, and a cooling device for cooling the reaction vessel receiving element. The invention is characterized by the fact that the reaction vessel receiving element is divided into several segments. The individual segments are thermally decoupled from one another, and each segment is assigned a heating device which may be actuated independently of the others. By means of the segmentation of the reaction vessel receiving element, it is possible for zones to be set and held at different temperatures.

  • Patent number: 8344733
    Abstract: A sample measurement device (110), in which a biosensor (30) having an electrode is mounted, voltage is applied to the electrode, and the concentration of a specific component in a sample deposited on the biosensor (30) is measured, comprises a voltage source (19) configured to apply voltage to the electrode, a time measurement component (22), and a controller (18) configured to control the voltage to be applied and measure the concentration of the specific component. The time measurement component (22) measures a detection time, which is the length of time between the mounting of the biosensor (30) and the deposition of a sample on the biosensor (30). The controller (18) changes a set value for measuring the concentration of a specific component according to the detection time. Consequently, measurement accuracy can be improved regardless of the temperature of the biosensor (30).
