ABSTRACT:
A time-of-flight mass spectrometer includes a detector and is adapted to measure the time it takes for an accelerated ion to reach the detector and thereby measure the mass of the ion. The time-of-flight mass spectrometer scans a voltage applied to an ion incident side surface of the detector in accordance with a mass to be measured. An electrode is provided between the detector and a space in which an ion flies. The time-of-flight mass spectrometer is capable of measuring ions of a wide range of masses with high detection efficiency by scanning a voltage applied to the electrode.
