    摘要： According to an aspect of the present invention, there are provided an ion trap mass spectrometry method and an ion trap mass spectrometry device using a mass spectrometer, the mass spectrometer including: an ion source part for ionizing a sample; an ion trap part for trapping ions generated in the ion source; a main high frequency power source for applying a main high frequency voltage to the ion trap part, and an auxiliary high frequency power source for applying an auxiliary high frequency voltage thereto; and a detector for detecting the ions ejected from the ion trap. The ion trap mass spectrometry method and the ion trap mass spectrometry device includes the steps of: accumulating desired ions into the ion trap part by ejecting undesired ions while accumulating ions into the ion trap part; and ejecting undesired ions that remain in the ion trap part and leaving the desired ions in the ion trap part are repeated alternately.

    摘要： Performing an MS3 with a tandem mass spectrometer causes problems of increase in size of the device and of increase in cost. Likewise, a plural number of times MS/MS analyses are even more difficult. An electrode to create a harmonic potential is disposed in a collision cell, and fragment ions produced by the first-time collision induced dissociation are accumulated in the harmonic potential. Target ions of the subsequent stage are let out, by means of an axial resonance excitation, selectively from the accumulated ions. The ions are excited in the axial direction to have a potential exceeding the harmonic potential. Thereby, the second-time collision induced dissociation is performed by means of a potential difference provided at the subsequent stage. In addition, an operation to return the ions back to the harmonic potential enables a plural number of times MS/MS analyses to be performed.

    摘要： An ion resonance condition is corrected accurately in an ion trapping device. Measurements are repeated by alternately applying and not applying a resonance frequency voltage while spectral data is obtained continuously. Data obtained in the absence of the resonance frequency voltage is used as reference data to correct the set data of a resonance condition. As a result, calibration can be made while taking into consideration the variations in the amount of ions that are introduced into the ion trap.
