Abstract: Stepped portions of a flow channel are reduced by completely fixing the channel that extends to the measuring unit, and reducing connections in the channel, thereby to suppress a disturbance in the flow of the liquid suctioned into the measuring unit. A means is provided so that the reaction solution and reagent suctioned will move towards the channel through which the liquids are suctioned.

Abstract: Disclosed is an automatic analyzer that is capable of executing a plurality of different measurement sequences in a sequential, parallel manner, has a check function for avoiding simultaneous mechanical equipment use and interference between the mechanical equipment, incorporates a plurality of different transport mechanism operation schemes for transporting a reaction vessel to the mechanical equipment, and minimizes a decrease in the throughput by choosing an appropriate transport mechanism operation scheme as needed. Before initiating a measurement sequence for a requested analytical test, the automatic analyzer checks for simultaneous use of the mechanical equipment. If it is judged that simultaneous mechanical equipment use would result, the automatic analyzer postpones the start of the requested analytical test. This makes it possible to avoid simultaneous mechanical equipment use and make a proper analysis.

Abstract: This invention provides an analyzer that uses magnetic particles, the analyzer being capable of removing inhibitors within a short time and reducing an analytical time. Magnetic particles 3 within a pre-washing solution accommodated in a reaction container 127 are aggregated by a magnet 4 disposed near the outside of the reaction container 127. The reaction container 127 is repetitively rotated by a container-rotating gear driving motor 9, thereby to impart vibration to the aggregated magnetic particles 3. The vibration changes relative positions of the magnetic particles densely populated by magnetic fields, and thus the inhibitors and other substances included in the magnetic particle aggregate can be removed from the magnetic particles.

Abstract: A photomultiplier tube is susceptible to noise at a low concentration and to saturation at a high concentration. It is necessary to make a measurement with an appropriate intensity of light to provide good reproducibility and linearity. Only adjustment of reagent concentration and constituents are not sufficient to apply the photomultiplier tube to a wide range of concentration. When the sensitivity of the photomultiplier tube is to be adjusted by voltage, measurement is performed under the optimum condition by setting a voltage to be applied suitable for measurement according to a concentration range specified for measurement items and adjusting the voltage based on selected items, previous values for the selected items, diagnostic information, etc.
