Abstract: Provided is a sample container and a gas chromatograph capable of detecting the pressure in the flow path for supplying a pressurized gas into a flow path. The ample supply device includes and insertion tube, a pressurized gas supply unit, a valve, and a pressure sensor. The pressurized gas supply unit is connected to the insertion tube via the flow path. The valve opens and closes the flow path. The pressure sensor senses the pressure between the valve and the insertion tube in the flow path. In the sample supply device, the pressure in the flow path connecting the pressurized gas supply unit and the insertion tube is detected, based on the detection signal from the pressure sensor in a state in which the valve is closed, and the insertion tube is inserted into the space in the sample container, before supplying a pressurized gas by a pressurized gas supply unit.

Abstract: A cell picking device includes a stage, a sucker, a driver, a work content receiver, a registrar and a device controller. A sample container is placed on the stage. The driver is provided to execute sample scraping work and sample sucking work using a pipette tip attached to the sucker. In a case in which selection of work contents of the driver is received by the work content receiver, a work procedure including the received work contents of the driver is registered by the registrar. The work of the driver is controlled by the device controller in accordance with the registered work procedure.

Abstract: A cell collecting device include a pipette tip that sucks substances in a cell culture container, a first valve connected to the pipette tip through a first flow path, a first pump connected to the first valve through a second flow path, and a second pump connected to the first valve through a third flow path. In a remove mode, the first valve is switched to connect the first flow path and the second flow path to each other and disconnect the third flow path, and the first pump is driven to discharge waste in the cell culture container, that has been sucked from the pipette tip, from a drain of the first pump through the first flow path and the second flow path, and in a picking mode, the first valve is switched to connect the first flow path and the third flow path to each other and disconnect the second flow path, and the second pump is driven to suck cells in the cell culture container using the pipette tip.

Abstract: A signal intensity based on a total ion current signal or the like is calculated from mass spectra obtained by a normal mode of mass spectrometric analysis. When the signal intensity has exceeded an intensity threshold, the beginning time T0 of a chromatogram peak is estimated from that signal intensity as well as one or more previous signal intensities. An MS2 execution permission-beginning time Ts is calculated by adding, to the beginning time T0, a delay time Tdelay determined front a half-value width of the peak estimated according to an LC separation condition. At or after the point in time where the actual time passes Ts, a peak which satisfies a precursor-ion selection condition is selected on a mass spectrum obtained by the mass spectrometric analysis. Then, an MS2 analysis with the m/z of the selected peak as the target is immediately performed to obtain an MS2 spectrum. By appropriately determining the delay time Tdelay, a high-sensitivity MS2 spectrum for a target component can be obtained when the concentration of the target component has become sufficiently high, and the accuracy of a qualitative determination or structural analysis of the component is thereby improved.

Abstract: A moving mechanism and a spray mechanism are controlled to spray a reagent from a nozzle to a sample plate while relatively moving the sample plate and the nozzle. The reagent is applied to an entire application area by moving a spray spot of the reagent sprayed from the nozzle, on the sample plate from a start point to an end point. At this time, the spray spot is moved in a sample placement area after a spray amount of the reagent from the nozzle and a moving speed of the spray spot become constant.

Abstract: In the touch panel device, when a slide operation in an oblique direction by a user is performed, out of a content displayed on the display screen 11 at that time, a region surrounded by an imaginary rectangle in which a start point Pa and an end point Pb of the slide operation are opposing corners and either one side of the imaginary rectangle is parallel to either one side of the display screen is displayed in an enlarged manner so as to fill the entirety of the predetermined region 12 of the display screen 11. With this, an intuitive display enlargement operation can be performed even for a touch panel device not supporting a multi-touch operation.
