Abstract: The mixing of reagents with each other in the reagent storage flow paths of an automatic analyzer is suppressed before and after exchange of the reagents, which are capable of being replenished without stopping analysis. An exchangeable reagent container that accommodates a reagent is connected to a reagent storage flow path that stores a portion of the reagent. The reagent storage flow path has first and second flow paths in which the second flow path is branched from the first flow path. A reagent syringe applies a negative or a positive pressure to the first and second flow paths; and a valve controls the flow path through which the reagent is sent. As a result, the reagent supplied to a measurement portion at a predetermined timing is switched from the reagent container to the reagent storage flow path wherein the reagent can be supplied without stopping analysis.

Abstract: A highly reflective light-guide system has a highly reflective light-guide surface for reflecting light that has been emitted from a sample and has entered from an entry port opposing a window material and propagating the same to an exit port opposing a light reception surface of a photodetector. An optical filter is provided in a space surrounded by the window material, the photodetector, and the highly reflective light-guide system and transmits the signal luminescence to be measured that is emitted from the sample between the window material and photodetector. The optical filter is fixed to the window material or photodetector by an adhesive, and the peripheral shape of the optical filter is smaller than the shape of the inside of a fitting part to which the optical filter is fitted and that is formed on the highly reflective light-guide system.

Abstract: When a sample of biological origin in an aqueous solution is used as the measurement medium in analysis using an electrochemical process, and a voltage of +1.2 V or greater (with saturated silver-silver chloride electrode potential as a reference) is applied, there are instances in which bubbles are observed to be produced within the flow cell, due to an electrolysis reaction deriving from the measurement buffer. There is a possibility that bubbles produced on the electrode will cover the electrode surface, reducing the effective surface area of the electrode. Also, the distribution of magnetic particles captured on the electrode will be disturbed by the gas produced thereby, lowering the reproducibility of the results of the analysis. Deaeration of the measurement medium prior to introduction of the measurement medium into the detector minimizes the effects of bubble production in degrading the analytical capability makes it possible to carry out highly sensitive electrochemical analysis.

Abstract: In conventional automatic analyzers, there have been instances where, when a plurality of associated items are analyzed as a set item, there is high variation in the analysis data obtained using the set item, leading to a need for improvement of analysis precision. The present invention comprises performing, in mutual association, a set of preparation steps to carry out until it is time to analyze an unknown sample, the set of preparation steps including a pre-preparation step in which stirring, etc., is performed when an analysis reagent kit is mounted on the analyzer, and a step for correcting a standard curve in which correction samples that correspond to analysis items are used. This makes it possible to perform analysis after the preparation states of a plurality of analysis reagent kits are collected as needed, enabling high-precision analysis of a set item.

Abstract: Provided are an automated analyzer for analyzing a substance contained in an unknown sample and a liquid reservoir, the analyzer and the reservoir being capable of saving users' operation without remarkably increasing the number of components. A flow path outlet of an overflow portion of the liquid reservoirs projects closer to the inner circumferential side of a drain flow path than to an inner circumferential surface side of an outer wall of the drain flow path serving as a destination to which liquid overflows. In addition, the flow path outlet projects so as to come into contact with an outer wall of the inner pipe. The flow path outlet of the overflow portion projects into the drain flow path so as to be located below an upper end of the outer wall of the drain flow path.
