Abstract: An automatic analyzer and a dispensing method for samples are provided that can reduce a dead volume amount while keeping up monitoring of a dispensing process. An automatic analyzer analyzing samples, comprises a sample dispensing mechanism 105a having a sample dispensing nozzle 116a dispensing the samples from sample containers 110, a sample container type discrimination section 303 obtaining information on the sample containers 110 and discriminating the type of the sample containers 110, a pressure sensor 202a detecting pressure in the sample dispensing nozzle 116a, a memory section 304 memorizing plural determination criteria data for use in determining presence/absence of an abnormality of the sample dispensing mechanism 105a for each type of the sample containers 110, and an abnormality determination section 305 determining, based on detection results of the pressure sensor 202a when dispensing the samples by the sample dispensing mechanism 105a and the determination criteria data corresponding to the type of the sample containers 110 which is discriminated in the sample container type discrimination section 303, whether or not an abnormality takes place in dispensing the samples.

Abstract: An automatic analyzer and a dispensing method of an reagent are provided, in which a troubleshooting time by an operator can be reduced to a shorter one than before. A control device 115 in an automatic analyzer 1: determines from a pressure value of a pressure sensor 202b whether there is an error in dispensing; determines from a capacitance value detected by a capacitance detection mechanism 117b whether a reagent dispensing nozzle, after its lowering is stopped, reaches the liquid level of a reagent; and decides a processing content for the reagent container from results of the determination on whether there is an error in the pressure and the liquid level detection determination.

Abstract: The purpose of the present invention is to provide an automatic analysis system which, even when a large number of quality control samples is necessary, reduces the time necessary for quality control. To this end, this automatic analysis system is provided with multiple analysis devices (190), a conveyance unit (120) to which the analysis devices (190) are connected, and an operation unit (101) which operates the conveyance unit (120) to convey samples to the analysis device (190), wherein the automatic analysis system has a common storage cabinet (210) for storing the quality control samples that can be supplied to the multiple analysis devices (190), and in accordance with a rule registered in advance for each of the multiple analysis devices (190), the operation unit (101) operates the storage cabinet (210) to automatically convey a quality control sample to an analysis device (190).
