Abstract
A precursor ion selected by a quadrupole mass filter is fragmented by imparting a predetermined amount of collision energy (CE) to the ion. Among the thereby generated product ions, only the ions included within a predetermined m/z range are stored in an ion trap. The ions are subsequently separated and detected by a TOF. For one precursor ion originating from a target compound, a mass spectrometric analysis is performed for each combination of a plurality of the set CE values and subdivided m/z ranges to obtain spectrum data. A spectrum data accumulator accumulates the spectrum data obtained by the mass spectrometric analysis under different combinations of (CE value, m/z range). Based on the accumulated spectrum data, a mass spectrum creator creates a single product-ion spectrum corresponding to the target compound.
