- the computer 800 that receives this command displays a message on the monitor 900, such as “Abnormal pressure. Check if the piping system is clogged. Prompt.
- the operator can operate the keyboard 810 to arbitrarily view the log of the pressure value during the pump operation as a graph on the monitor 900.
- control unit 700 detects the occurrence of an abnormality in the pressure state by determining the pressure state detected by pressure sensor 500 at a specific timing of the operation of pump 600. The detection of the occurrence of an abnormality in the pressure state is performed by comparing the output value (output voltage) of the pressure sensor 500 with a predetermined reference value (reference voltage).
- control unit 700 causes monitor 900 to display a message indicating the occurrence of the abnormality in the pressure state via computer 800.
- the pump 600 repeats the suction / discharge operation a specified number of times, proceeds with no / evolution, and finally, the reaction result is obtained by the CCD camera 1000.
- the computer 800 controls the CCD camera so that the CCD camera 1000 takes a picture synchronously when the pump 600 completes the suction operation of 50 ⁇ and the reaction liquid completely disappears from the reaction chip 103. Control 1000.
- control section 700 When detecting the occurrence of an abnormality in the pressure state, the control section 700 returns the pump 600 in the pressure state to the initial state, performs an end process, and displays on the monitor 900 a message for suspending the hybridization. You can return the command to computer 800.
- control unit 700 controls the pump 600 based on the pressure state detected by the pressure sensor 500, and continues the hybridization while the pressure state is normal.
- the pump 600 is driven and an abnormality in the pressure state is detected, the pump 600 is stopped.
- pressure state detected by pressure sensor 500 may be constantly displayed on monitor 900.
- the description has been made on the assumption that the operating speed of the pump 600 is constant, and that the reaction liquid permeability of the reaction chip 103 to be used and the viscosity of the reaction liquid are always constant.
- the pressure of the reaction solution driving tube 400 becomes Greatly varies depending on the combination of If the reaction liquid permeability of the reaction chip 103 is very good and the viscosity of the reaction liquid is low, the operating speed of the pump 600 should be increased.
- the operation speed of the pump 600 is increased and the reaction liquid is driven. If this happens, a large strain load is applied to the reaction chip 103, and in the worst case, the reaction chip 103 may be damaged. If the operating speed of the pump 600 is set to always low so that the reaction liquid permeability is the worst and the viscosity of the reaction liquid is the lowest and the reaction chip 103 is not damaged in the combination, the reaction liquid driving time This can happen.
- the operating speed of the pump 600 is varied within a predetermined range so that the pressure of the reaction liquid driving tube 400 falls within a predetermined range. This can also be realized without changing the configuration of the present embodiment by simply changing the control program.
- the operator turns on and initializes each device by turning on a main switch (not shown). At this time, a failure check operation of the piping system is performed at the same time. You may. Specifically, after the reaction device confirms that the reaction vessel is not mounted, the control unit 700 instructs the pump 600 to perform a suction operation, and at the same time, the digital data 701a transmitted from the A / D converter 701— Based on 701d, calculate with reference voltage to determine the force that is below specified voltage value. If the piping system is clogged or the pressure transmission medium is deteriorated to have a high viscosity, the calculated voltage will be higher than specified. Since the reaction vessel is not mounted, it can be determined that the reaction apparatus has an abnormality in the piping system.
- the test of a gene reaction using a DNA chip has been described as an example.
- the present invention provides a substrate on which a probe for testing a bio-related substance other than a gene is immobilized.
- the present invention may be applied to the detection of other biologically-related substances using other test chips made of, for example, tests for immune reactions and the like.
- various types of substrates can be applied to a substrate on which various probes are immobilized.
- a two-dimensional substrate such as a silicon wafer or glass, various beads, various porous substrates, and various gels can be applied.
