  • Patent number: 10101346
    Abstract: In accordance with embodiments, a transport mechanism transports a first sample container to a sample aspiration position. A setting part may set a second sample container, that accommodates a sample to be measured, with priority over a measurement of a sample in a first sample container. A nozzle may be capable of moving a sample from a first sample container at a sample aspiration position, and aspirating the sample from the second sample container. A detector may detect components of the sample. A controller may control a transport mechanism such that the first sample container moves to a position distant from the sample aspiration position, when the first sample container has been transported and when sample aspiration of the second sample container is required. A controller may execute control to move the nozzle above the sample aspiration position in state in which the first sample container is distant from the sample aspiration position.

  • Patent number: 10099866
    Abstract: A transport apparatus transports sample holder racks. The apparatus employs a first transport unit that moves the rack in a path between two ends of the transport apparatus, a rack sender unit that extends in a first direction that intersects the path, a second transport unit dimensioned parallel to the first transport unit and with the rack sender unit interposed therebetween, which locates the sample container held in the rack at a sample loading position of a measurement device, and a first movable member capable of moving in the first direction between the first and the second transport units. The apparatus has movable portions that alternately stop the rack movement, and push the rack such that optimal movement is achieved whereby the rack moves beyond the rack sender unit to the second transport unit as the first movable member moves in the first direction.

  • Patent number: 9829497
    Abstract: A sample analysis system includes a first measurement unit, a second measurement unit arranged to a downstream side of the first measurement unit, and an information processing section which obtains a measurement result of a sample. The information processing section determines, based on the measurement result of the sample measured by the first measurement unit, whether or not a retest of the sample by the first measurement unit is necessary. When the retest by the first measurement unit is necessary, the information processing section causes the sample container to be transported to a first sample supply position for the first measurement unit and causes the first measurement unit to perform measurement of the sample.
