Abstract: An analysis unit 111 for automatically analyzing a sample comprises a sample dispensing nozzle 2 for dispensing the sample and an electrolyte measurement unit 114 for carrying out internal standard liquid measurement one or more times at least before measuring the electric potential of the sample. If the electrolyte measurement unit 114 is to carry out the electric potential measurement of the sample in succession, a different internal standard liquid measurement operation is carried out before the electric potential measurement than if the electric potential measurement is not to be carried out in succession and there are to be gaps between measurement intervals. This results in the provision of an automated analyzer, automatic analysis system, and automatic sample analysis method that make it possible to reduce the influence of ambient temperature on electrolyte measurement, ensure measurement accuracy, and enhance overall device processing capacity.

Abstract: Provided is an automatic analysis device that can suppress concentration of a reagent made to react with a specimen. This automatic analysis device is provided with: a reagent container which accommodates a reagent and which has attached thereto a perforable lid; a perforation unit for perforating the lid; and a reagent suction nozzle that is inserted into a hole formed by perforation and that sucks up the reagent. The automatic analysis device is characterized by being further provided with a state storage unit that stores the state as to whether the reagent container is in an unused state or in a used state, and a state update unit that, when the lid is perforated by the perforation unit while the reagent container is in an unused state, updates the state stored in the state storage unit to the used state.

Abstract: An automatic analyzer is capable of transporting a sample at an optimum timing and a method of transporting the sample. An automatic analyzer includes an analysis unit which measures a sample, a transport unit which transports the sample to the analysis unit, and a control unit which controls the analysis unit and the transport unit. A sample is transported to the analysis unit by a time of starting an aspirating operation on the sample by allowing the analysis unit to perform a pre-measurement operation for each measuring method which needs to be performed before aspirating the sample even when the sample is still in the transport unit.

Abstract: An automatic analyzer is capable of ensuring sufficient nozzle cleaning and suppressing of deterioration in the accuracy of analysis. When it is judged that there remains no analysis item of the sample, a judgment is made on whether the sample dispensation quantity of the n-th sample dispensation is less than a dispensation quantity threshold value or not, and if less, a cleaning pattern is selected by making a judgment on whether or not all the sample dispensation quantities of the first through (n?1)-th sample dispensations are less than the dispensation quantity threshold value. If the sample dispensation quantity of the n-th sample dispensation is the dispensation quantity threshold value or more, another cleaning pattern selected by making the judgment on whether or not all the sample dispensation quantities of the first through (n?1)-th sample dispensations are less than the dispensation quantity threshold value.

Abstract: Please substitute the new Abstract submitted herewith for the original Abstract: The present invention reduces the turnaround time of an automated analyzer. During a period when cyclic measurement by a measurement unit is unnecessary, a controller washes a reaction vessel using a washing cycle having a cycle time shorter than that of an analysis cycle. A single analysis cycle and a single washing cycle both include a reaction disc stopping period and rotation period. In the washing cycle, there is no time during the stopping period when a sample dispensing mechanism, reagent dispensing mechanism, or stirring mechanism operates but there is a time when a washing mechanism operates. The washing cycle stopping period is shorter than the analysis cycle stopping period. The amount of rotation of the reaction disk in the analysis cycle rotation period is the same as the amount of rotation of the reaction disk in the washing cycle rotation period.
