Abstract:
An orthogonal acceleration time-of-flight (TOF) mass spectrometer in which an ion injected into an orthogonal acceleration area is periodically accelerated in a direction orthogonal to a direction of the injection and thereby ejected into a flight space. The mass spectrometer includes: an orthogonal acceleration electrode; a voltage supplier for applying a fixed level of voltage to the orthogonal acceleration electrode with a predetermined period; a TOF determiner for detecting an ion after a completion of a flight of the ion within the flight space, and determining the TOF of the ion; a storage section in which mass determination information defining a relationship between the TOF and mass-to-charge ratio of the ion depending on the period of the applied voltage is stored; and a mass-to-charge-ratio determiner for determining the mass-to-charge ratio of an ion from the TOF of the ion determined by the TOF determiner, based on the mass determination information.

Claim (Index 5):
An orthogonal acceleration time-of-flight mass spectrometer in which an ion injected into an orthogonal acceleration area is accelerated in a direction orthogonal to a direction of the injection and thereby periodically ejected into a flight space, and a mass-to-charge ratio of the ion is determined based on a time of flight of the ion within the flight space, the mass spectrometer comprising:\n a) an ion transport electrode for transporting an ion into the orthogonal acceleration area; b) an orthogonal acceleration electrode including a pair of electrodes arranged in such a manner as to face each other across the orthogonal acceleration area, for accelerating an ion injected into the orthogonal acceleration area, in the direction orthogonal to the direction of the injection; c) a flight-path-defining electrode including a flight tube arranged on an outer edge of the flight space; d) a storage section in which applied-voltage information which is a set of information concerning levels of voltages applied to the orthogonal acceleration electrode, the ion transport electrode, and the flight-path-defining electrode is stored, where an applied voltage whose level changes depending on an ion-ejection period is related to at least the orthogonal acceleration electrode, the ion transport electrode, or the flight-path-defining electrode in the applied-voltage information; and e) a voltage supplier for applying voltages to the orthogonal acceleration electrode, the ion transport electrode, and the flight-path-defining electrode, based on the applied-voltage information.
