Abstract: In the present invention, an analysis schedule is pre-created such that streams of a plurality of liquid chromatograms can operate in parallel and a mass spectrometer can collect data at the timing of each component elution. A control unit controls so as to: divide the time required to analyze each sample in a plurality of liquid chromatogram systems into pre-collection time, time during collection, and post-collection time; search and allocate time positions in which the time during collection in the liquid chromatogram units do not overlap; determine start times for the plurality of liquid chromatogram units to thereby create an analysis schedule; and thereafter perform analysis. The control unit further stores parameter sets for varying component elution times, adjusts analysis parameters so as to make data collection timings appropriate for creating an analysis schedule, and changes the component elution times.

Abstract: When automatically classified results are different from judgment of a laboratory technician, the laboratory technician has to reselect the bacterial colonies one-by-one to be a pickup colony through watching the displayed image. To get rid of the inconvenience, provided is a pretreatment device for a bacteria test comprising: a specification unit by which an operator instructs to specify the number of bacterial colonies and the increased/decreased number of the bacterial colonies to be displayed; and a display unit for displaying classification results obtained following the operator's instruction. The pretreatment device for a bacteria test facilitates the automatically classified results to be brought close to the judgment of the laboratory technician, resulting in the saving of the time required for checking the appropriate bacterial colonies for the pickup colony.

Abstract: The present invention relates to a nucleic acid analysis device in a nucleic acid analysis apparatus, whereby waste of reaction spots on the nucleic acid analysis device is eliminated and leakage of fluorescence excitation light to unobserved nucleic acid measurement regions is minimized. Specifically, the nucleic acid analysis device has a plurality of nucleic acid measurement regions, which are characterized in that one nucleic acid measurement region is disposed at a sufficient distance from the other nucleic acid measurement regions such that the other nucleic acid measurement regions do not enter an irradiation region.
