摘要： A mass spectrometer includes a linear multipole electrode, an auxiliary electrode that applies a DC potential on the center axis of the linear multipole electrode, and a DC power supply that supplies a DC power to the auxiliary electrode. The DC potential slope formed on the center axis of the multipole electrode is changed according to the measuring condition. The ejection time of ions can be adjusted optimally by adjusting the potential slope so as to satisfy the measuring condition. If the ejection time of ions is shortened, confusion of different ion information items that might otherwise occur on a spectrum can be avoided. If the ejection time of ions is lengthened, detection limit exceeding can be avoided and ions can be measured efficiently, thereby highly efficient ion measurements are always assured.

摘要： There has been a problem that both detection sensitivity and throughput cannot be improved simultaneously by a conventional MS/MS analysis method.A mass analyzer having an ion trap for ejecting ions in a specific mass range, a collisional dissociation part for causing ions ejected from the ion trap to be dissociated, a mass analyzing part for performing a mass analysis of ions ejected from the collisional dissociation part, and a control part including a list in which measurement conditions for each ion are stored selectively resonance-ejects ions introduced into and accumulated in the ion trap based on masses. A scanning operation is a repetition of an operation of ejecting specific precursor ions in a direction of the collisional dissociation part and an operation of ejecting nothing, and each ion can be measured under optimal measurement conditions by controlling an output voltage of each part with reference to list information, realizing a mass analyzer that can perform an MS/MS measurement with high throughput and high sensitivity.
