An automatic analyzer is provided which is easier to investigate when some troubles such as data abnormality occur in a sample analysis result as compared with an automatic analyzer according to the related art. The automatic analyzer includes: analysis units that perform analysis and quality control analysis for ensuring quality of the analysis; a storage medium that stores quality control results of the quality control analysis performed by the analysis units; a monitor that displays the quality control results; and a control PC that controls an operation of the analysis units (8, 9, and 16), executes, when an arbitrary result is selected from the quality control results stored in the storage medium, based on the selected quality control result, statistical calculation of the selected result and a quality control result performed in the past, and causes the monitor to display a statistical calculation screen as a statistical calculation result.

The invention includes sample preparation cartridges and apparatuses. The invention provides means for lysing and optionally selectively capturing at least one compound in a sample to purify, concentrate, and/or select for the at least one compound. The invention can be used in conjunction with a sample processing instrument to create a fully-automated or near-fully-automated sample workflow.

A collecting system is provided that can include a probe configured to collect pathogens from a surrounding fluid, an elution chamber containing a liquid solvent and configured to receive the probe to elute the pathogens collected on the probe using the liquid solvent, and a heater configured to lyse the pathogens to release the genetic material of the pathogens into the liquid solvent.

Apparatuses and methods to mix and reconstitute materials into a suspension may include a base containing a motor and a head unit for holding one or more sample containers to be mixed. The motor may include a shaft connected to the head unit for effecting displacement of the sample containers in multiple directions for mixing the materials to be reconstituted. The sample containers may contain a solid to be mixed, such as in powder form, and a diluent liquid to be mixed. The sample containers may have releasably attached and received therein, and the head unit can restrain radial motion of the sample containers such that the sample containers are maintained in an upright orientation. The frequency of the motor and the magnitude of the displacement effected by the motor may be adjusted. At least two of the multiple directions of the displacement can be substantially perpendicular.

The automatic analyzer includes: a sample dispensing unit that dispenses a sample into a reaction vessel; a reagent dispensing unit that dispenses a reagent into the reaction vessel; a control unit that controls the sample dispensing unit and the reagent dispensing unit; and a measurement unit that measures a mixed solution of the sample and the reagent mixed in the reaction vessel. The reagent includes three types of reagents of: a first reagent that specifically binds to an antigen in the sample; a second reagent that specifically binds to a site different from that to which the first reagent binds with respect to the antigen and has a label to be detected by the measurement unit; and a third reagent that specifically binds to a site different from the binding site of the first reagent and the antigen and contains insoluble carriers.

An intelligent experimental device for collaborative mining of associated resources includes a signal transmission mechanism, a pressure maintaining mechanism, a feeding mechanism, and a reaction mechanism.

The pressure maintaining mechanism includes ambient and axial pressure oil chambers, ambient and axial pressure pumps, ambient and axial pressure liquid distribution tanks, a comprehensive pressure distribution pipe, and hydraulic transmission pipes. The feeding mechanism includes monitoring analyzers, temperature controllers, solution transfer pipes, seepage pumps, mixture conveying pipes, a comprehensive liquid distributor, an aggregate chamber, a liquid chamber, an oil chamber, a gas chamber, a mixing chamber and an analytical purifier. The reaction mechanism includes a uranium mine cavity, a coal seam cavity, an oil-gas cavity, nuclear magnets, thermohydraulic sensors, and shearing gaskets.

Method and compositions using transition metal salts and/or ammonium chloride to liberate toxins and other molecules from cyanobacteria, useful for assaying for total cyanobacterial toxins in lakes, reservoirs and other waters.

A sample preparation cartridge for use with a sample preparation device, the cartridge includes a housing defining plural separate segments, at least one of said segments comprising a fixed section of a pipette component; and a moveable head comprising a pipette tip, the head being configured, in use, to be moved between a position in which the pipette tip is in sealed engagement with the fixed section of pipette component and a position in which pipette tip is positioned adjacent to another of said plural segments. With the present invention a disposable sample preparation cartridge and corresponding analytical reader can be provided in a very cost effective and simple manner whilst still ensuring high quality sample preparation for analysis.

An analyzer having an inner chassis surrounded by a housing includes sample and dilution probes, a mixing housing including first and second mixing chambers, a flow cytometer including a flow cell, and sample and sheath pumps configured to perform first and second pluralities of tasks, respectively. The first plurality of tasks includes: aspirating sample into the sample probe, dispensing sample from the sample probe into the first and second mixing chambers, delivering first sample-dilution fluid mixture to the flow cell, and delivering second sample-dilution fluid mixture to the flow cell. The second plurality of tasks includes: dispensing sheath to the flow cell in cooperation with the delivery of the first sample-dilution fluid mixture to the flow cell, and dispensing sheath to the flow cell in cooperation with the delivery of the second sample-dilution fluid mixture to the flow cell.
