  • Patent number: 11740254
    Abstract: The object of the invention is to provide an automatic analysis apparatus capable of setting a dispensing mechanism for measuring dispensing accuracy and a dispensing volume, and capable of performing dispensing accuracy measurement without absorbance measurement. Regarding a dispensing accuracy, a dispensing mechanism to be measured is designated. Parameters including a dispensing volume and the like are input. A dispensing operation of the input dispensing volume is automatically performed for each designated dispensing mechanism. A reaction vessel contains, for example, a reagent of the input dispensing volume which has been dispensed by the designated dispensing mechanism. By measuring a weight of the reagent in the reaction vessel, or the like, it is possible to measure the dispensing accuracy of the designated dispensing mechanism.

  • Publication number: 20230251253
    Abstract: An electrochemiluminescence method of detecting an analyte in a liquid sample and a corresponding analysis system. An analyte in a liquid sample is detected by first providing a receptacle containing a fluid comprising protein coated magnetic microparticles to a stirring unit. Stirring of the fluid is necessary since the density of the microparticles is usually higher than the density of the buffer fluid. Thus the microparticles tend to deposit on the bottom of the receptacle leading to an aggregation of the microparticles because of weak interactions. To obtain representative measurements a homogeneous distribution of the microparticles in the buffer fluid is necessary to ensure a constant concentration of microparticles for each analysis cycle. It is further necessary to provide disaggregation of the microparticles, which is also realized by stirring the fluid. Stirring is conducted with a rotational frequency that is adapted to the amount of fluid to be stirred.

  • Patent number: 11519924
    Abstract: In order to aspire to higher sensitivity in an automatic analysis device, it is important to prevent the mixing of dust and the like in a reaction part in which a sample and a reagent react. The present invention presents an automatic analysis device that is provided with a configuration for making the pressure inside a specific block in the device such as a reaction part, or inside the device become positive. By making the pressure become positive and forming an air flow that flows out from the inside of the reaction part or the device, it is possible to limit, to a certain amount or less, the amount of dust penetrating into the reaction part.
