    摘要: A mass spectrometer and a mass spectrometry method having a high ion selection efficiency are provided. The mass spectrometer comprises an ion trap, a sample introducing device, an electron gun, a detector, a power supply for applying voltage to the ion trap, a control device for controlling the power supply and the electron gun, a mass analyzing device for performing mass spectrometry based on a detected signal of the detector. Using an auxiliary power supply, direction of an auxiliary electric field generated between end cap electrodes is made to point only toward the detector. In this occasion, by setting the cycle of the auxiliary voltage near the oscillation cycle of interest ion species in the axial direction, the interest ion species are synchronized with the auxiliary electric field to be certainly unstabilized in the detector side.

    摘要: There is provided a method for diagnosing an abnormal state of a sensor having a nonlinear output characteristic in which an output signal of a sensor changes nonlinearly. The method includes the steps of determining a first detection value which is indicated by the output signal of the sensor at a predetermined time, and determining a second detection value which is indicated by the output signal of the sensor obtained when a detection value indicated by the output signal has changed by a predetermined variation from the first detection value. The method also includes judging whether or not a deviation between the first detection value and the second detection value is out of a predetermined range, and determining that the sensor has an abnormal state when it is determined that the deviation is out of the predetermined range.
