Abstract: A light source radiates light onto a reaction vessel in which a sample is caused to react with a reagent. A transmissive-light receiver, located across from the light source with the reaction vessel located therebetween, measures the intensity of transmissive light passing through the reaction vessel. Scattered-light receivers, located on the side of the transmissive-light receiver, are used to measure the intensities of scattered light and scattered light generated from the reaction vessel. Based on the results of the measurement by the scattered-light receivers, the light intensity of the light source is corrected. This allows correction of the intensity of the light incident on the reaction vessel even when an analysis involves the use of scattered light. The use of such analyzers prevents analysis results from varying from analyzer to analyzer due to inaccurate measurement of the incident light.

Abstract: An automatic analyzer is capable of reducing the influence of scattered light having noise components to enhance the S/N ratio properties of a light reception signal. Data is obtained at a plurality of angles by a plurality of detectors and a signal obtained by one detector selected from among the detectors is selected as a reference signal. An approximation is applied by an approximation selection unit, and an approximation calculation unit calculates an approximation using the selected approximation. A degree of variability of the reference signal is determined and a data correction unit corrects the signal of the detector by dividing the signal of the detector by the degree of variability of the reference signal. A concentration calculation processing unit performs the concentration calculation by use of the corrected signal data, and a result output unit outputs the results on a display.

Highly reliable concentration analysis with little effect from noise components can be achieved by calculating the correlation between scattered light detected by a plurality of light detectors before calculating concentration, and by performing concentration analysis using scattered light with high correlation.

Abstract: It is checked whether a liquid undulation prevention mechanism is present or absent in a reagent vessel at the start of an operation (steps 601 and 602). When the liquid leakage prevention mechanism is absent in the reagent vessel, the size of the opening of the reagent vessel is judged (step 604). A nozzle is inserted and lowered into the reagent vessel to judge the contact of the nozzle to the liquid surface. When the opening is larger size, a capacitance method is used (step 607). When the opening is small size, a pressure detection is used (step 608). When the liquid leakage prevention mechanism is present, the size of the opening is judged (step 604). When the opening is larger size, a capacitance method is used (step 605). When the opening is small size, a pressure detection is used (step 606).

Abstract: An automatic analysis system that, even if one module out of a plurality of analysis modules becomes analysis-incapable, allows the analysis to be continued without stopping the entire system. The automatic analysis system has a plurality of analysis modules 5, 6, 7, and 8, and a transferring line 3 for transferring specimens to these analysis modules. During the analysis operation by the entire system, each analysis module is controllable as a standby state, namely, as a single-body analysis module in a state of being independent and being cut off from the control of the entire system.
