An automatic analyzer is capable of normally maintaining a device condition and exhibiting a stable performance by automatically monitoring a cleaning implementation situation using a wash rack. The automatic analyzer includes an analysis unit, a rack loading unit into which at least a sample rack that holds the sample and a wash rack that holds a cleaning liquid are loaded. A transportation mechanism transports the sample rack and the wash rack to the analysis unit. A management control unit causes the wash rack to be transported to an analysis unit, causes a cleaning operation of the analysis unit by the cleaning liquid held by the wash rack, and causes stopping of the sample analysis operation of the analysis unit to which the wash rack has been transported until a performance of the analysis unit is determined to be normal based on the cleaning operation.

A quality control support method for displaying a control chart of quality control related to an analyzer that measures a subject sample, the method comprising: generating a first control chart showing results of measured quality control substances by the analyzer in a first period; receiving a designation of a second period different from the first period, the second period being shorter than the first period and at least partially overlapping with the first period; generating a second control chart showing results of the measured subject samples by the analyzer in the second period; displaying the generated first control chart; and displaying the generated second control, is provided.

To minimize cross talk in systems and methods for detecting two or more different optical signals emitted from each of a plurality of reaction receptacles, an excitation signal associated with each of the optical signals has a known excitation frequency, and any detected signal having a frequency that is inconsistent with the excitation frequency is discarded. The receptacles are moved relative to optical sensors configured to detect each unique optical signal from an associated receptacle, and to further minimize cross talk, the optical sensors are arranged so that only one reaction receptacle at a time is in a signal detecting position with respect to one of its associated optical sensors, and the optical sensors are grouped by the optical signal they are configured to detect so that a first optical signal is detected from each of the reaction receptacles before a second optical signal is detected from the reaction receptacles.

According to one embodiment, a method is for generating a calibration curve based on results of photometry on a plurality of standard samples each containing a detection target in a known concentration. The concentration differs between the standard samples. The method includes obtaining the results of photometry on the standard samples at different photometry timings, to generate the calibration curve.

An improved calibration process for a medical testing machine. The machine automatically recognizes that a package of calibration material has been inserted into it, and performs a calibration sequence to ascertain a calibration parameter to be used in performing future tests with the medical testing machine. The calibration package may include machine-readable indicators that the package is to be used for calibration, and of a calibration setpoint of a calibration material in the package. A calibration material may be stored in a lyophilized state in the package, and the medical testing machine may automatically reconstitute the lyophilized material.

Systems and methods for performing simultaneous nucleic acid amplification and detection. The systems and methods comprise methods for managing a plurality of protocols in conjunction with directing a sensor array across each of a plurality of reaction chambers. In certain embodiments, the protocols comprise thermocycling profiles and the methods may introduce offsets and duration extensions into the thermocycling profiles to achieve more efficient detection behavior.

According to one embodiment, a liquid dispensing apparatus includes a mounting unit configured to hold a liquid discharging apparatus that discharges liquid from nozzles simultaneously by an operation of an actuator. An inspection media placement region is provided on which an inspection medium can be placed to receive the liquid discharged from the liquid discharging apparatus. A controller is configured to control the actuator to vary a volume of the liquid discharged from each nozzle for a nozzle inspection operation. The volume is varied according to a predetermined distance between adjacent nozzles that simultaneously discharge liquid and a predetermined contact angle for a droplet of the liquid when on the inspection medium.

In order to allow an analyzer to be calibrated or a sampling channel to be purged without removing a sampling probe from a sampling location, provided are a sampling channel through which an exhaust gas from an internal combustion engine flows, an analyzer that is connected to the sampling channel and analyzes the exhaust gas, a diluter provided upstream of the analyzer in the sampling channel, a recirculated channel that branches from a branch point set between the analyzer and the diluter in the sampling channel and joins the diluter, a pump that is provided in the recirculated channel and guides part of the exhaust gas from the branch point to the diluter, an additional channel that is connected to the recirculated channel or the sampling channel and through which a calibration gas or a purge gas flows, and an opening and closing mechanism provided in the additional channel.

A high-throughput automatic analyzer integrates a biochemical analysis section and a blood coagulation analysis section. The analyzer is capable of achieving a reduction in size, system cost, and lifecycle cost. The automatic analyzer includes: a reaction disk; a first reagent dispensing mechanism that dispenses a reagent to reaction cells on the reaction disk; a photometer that irradiates a reaction solution in the reaction cell with light; a reaction cell cleaning mechanism; a reaction vessel supply unit that supplies a disposable reaction vessel for mixing and reacting a sample and a reagent with each other; a second reagent dispensing mechanism that dispenses a reagent to the disposable reaction vessel; a blood coagulation time measuring section that irradiates a reaction solution in the disposable reaction vessel with light to detect transmitted or scattered light; and a sample dispensing mechanism that dispenses a sample to the reaction cell and the disposable reaction vessel.
