摘要： PROBLEM TO BE SOLVED: To provide a function capable of acquiring easily an analysis result by simplifying an analysis work in order to grasp the present operation efficiency and an efficient operation form. SOLUTION: This automatic analysis system is equipped with analysis units for analyzing a sample, a conveyance mechanism for conveying the sample to the analysis unit, and a control mechanism for controlling the analysis units and the conveyance mechanism. In the system, a plurality of analysis units are connected to the conveyance mechanism. The system is also equipped with a storage means for storing information on at least the analysis item and the measuring day of each sample as much as a portion in a period of two days or longer. Since the system has a function for accumulating analysis request information utilized in daily analysis, an operation function and a screen for controlling them, the analysis work by an analyzer becomes possible, while omitting a work for prior information collection. In addition, prior acquisition of the analysis request information, information transfer to a dedicated simulator, result reflection to the analyzer or the like can be performed simply, and analysis can be performed at any time as the need arises, and the efficient operation form of the analyzer can be maintained.

摘要： PURPOSE:To prevent the change of properties and the condensation of a reagent by adding a substance into a container of the reagent which shuts the liquid surface of the reagent from the outside air. CONSTITUTION:At a production site of a reagent, a reagent 2a is filled in a reagent vessel 1a and a seal 6a resistive to medicines is tightly held in touch with the vessel 1a by means of a lid 5a, which is then packaged and preserved or brought in the market. At the using time, the lid of a vessel 1b is removed, so that a room 3b is opened to the air. In order to avoid this, a shutting agent 4a taken in a dispenser instrument 7g is added to the reagent 2b, so that the reagent is shut by a shutting agent 4c. Since the reagent 2b and room 3b are shut, the change of properties of the reagent 2b due to the oxygen and carbon dioxide in the air and the condensation of the reagent 2b as a result of the evaporation of moisture are solved. When the reagent is to be fed to an automatic analyzer, a reagent tube 8a connected to a dispenser device is inserted together with a weight into a reagent 2c. The reagent 2c is automatically consumed and consequently, the shutting agent 4c becomes lower. Nevertheless, the reagent 2c and a room 3c are still shut from the air. The property change and condensation of the reagent 2c are accordingly not given rise to.

摘要： PURPOSE:To improve reliability of analysis result by measuring sample amount before starting analysis and at the time of starting, monitoring sample evapora tion and correcting an evaporation amount. CONSTITUTION:A sampling arm 6 of a sample probe 5 integral with a liquid surface sensor mounted at the arm 6 falls according to a pulse signal to a pulse counting motor 8 for vertically driving the am, and the probe 5 senses a liquid surface. After sensing, the arm 6 rises under the control of a microcomputer. In this case, the microcomputer calculates a height from a bottom of a sample cup 1 to the liquid surface, converts it into a liquid amount and obtains a sample amount V1 in a cup 1 before starting the analysis. Similarly, a sample amount V1 at the time of starting the analysis is obtained. After a predetermined amount of the sample is gathered and reagent is added after the liquid surface is sensed, absorbance is measured. In this case, the amount V1 is compared with the amount V2 by an evaporation amount calculator 13 before starting the analysis and at the time of starting, the evaporation amount is calculated as to the sample decided as V1>V2, corrected as prescribed, and an analysis result is obtained.

摘要： PURPOSE:To sample a minute amount of specimen efficiently and highly accurately by detecting the level of a sample-shortage detecting region with a sample probe, which also serves the role of a liquid-level sensor, and controlling the depth of the tip of the probe and the driving of a syringe. CONSTITUTION:A sampling arm 5 is driven 6. A sampling probe 4, which also serves the roles of a liquid level sensor and a sampling nozzle, is brought into contact with the liquid surface of a specimen in a sample cup 10b, and the specimen is sampled. When the amount of the specimen is as minute as about, e.g. 20-30mul, the tip of the probe 4 is inserted down to the bottom of the cup 10b. Therefore, there is no dummy amount of the specimen, which is caused by the difference between the heights of both tips of the sensor and the nozzles, at all. The tip of the probe 4 is inserted beneath the liquid surface by the amount of the level after the tip of the probe 4 comes into contact with the liquid surface based on the level information in a sample-shortage detecting region from the bottom of the cup 10b. Therefore, the specimen is not attached. When the total amount of the specimen becomes lower than the maximum amount of the apparatus, the driving of a specimen sampling syringe 1 is controlled, and the sucking of air is prevented. Therefore, the sampling accuracy can be maintained.
