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.

Claim (Index 2):
A tandem mass spectrometer including: an ion source for ionizing a compound in a sample; a first mass separation section for selecting, as a precursor ion, an ion having a specific mass-to-charge ratio from various kinds of ions generated by the ion source; an ion fragmentation section for fragmenting the precursor ion by collision-induced dissociation; and a second mass separation section and a detector for performing a mass spectrometric analysis of various product ions generated by the fragmentation, the tandem mass spectrometer capable of temporarily storing ions by making the first mass separation section, the ion fragmentation section or the second mass separation section operate as an ion storage section, or by using an ion storage section placed between the first mass separation section and the ion fragmentation section or between the ion fragmentation section and the second mass separation section, the tandem mass spectrometer comprising:\n a) a collision energy setter for changing a collision energy imparted to the precursor ion for the collision induced dissociation in the ion fragmentation section to m levels, where m is an integer equal to or greater than two; b) a mass-to-charge-ratio range setter for changing a mass-to-charge-ratio range of the ions to be stored in the ion storage section to n ranges shifted along a mass-to-charge-ratio direction (where n is an integer equal to or greater than two); c) an analysis controller for setting one of the m levels of collision energy through the collision energy setter, for setting one of the n mass-to-charge-ratio ranges through the mass-to-charge-ratio range setter, and for controlling each section to perform a mass spectrometric analysis of the product ions for a predetermined precursor ion under a condition including the combination of the set level of collision energy and the set mass-to-charge-ratio range, the analysis controller further configured to combine each of the m levels of collision energy with an integer number of mass-to-charge-ratio ranges fewer than n among the n mass-to-charge-ratio ranges in such a manner that each of the n mass-to-charge-ratio ranges is selected at least one time, and to control each section to perform the mass spectrometric analysis of the product ions at least one time for each of all combinations whose number is equal to or greater than m or n, whichever is greater; and d) a data processor for accumulating spectrum data obtained by the mass spectrometric analysis of the product ions performed the number of times equal to or greater than m or n, whichever is greater, under a control of the analysis controller, to create one mass spectrum over a predetermined mass-to-charge-ratio range.
