  • Patent number: 9097690
    Abstract: In a large-scale analyzing system arrangement with a multi-sample processing capability, connecting a plurality of analyzing systems each having a minimum analyzer configuration makes it difficult for each analyzing system to continue analysis while managing and sharing the consumables information required for measurement between the analyzers. Additionally, since the sample preprocessing and conveying system does not recognize operational states of the analyzing systems during the analysis, conveyance of the sample to an analyzing system unable to conduct the analysis is likely to occur, resulting in delays in reporting the test results on the sample. The internal operational status of a plurality of analyzing systems is collectively managed and samples are conveyed between the analyzing systems. If the analysis is determined not to be capable of being continued, the sample is temporarily placed in a stand-by condition and then the analysis, after returning to a restartable state, is automatically continued.
