Abstract
A data acquisition method in a mass spectrometer includes a. providing an ion source to generate precursor ions; b. feeding the precursor ions into a first mass analyzer that selects one mass window such that the precursor ions located outside the mass window pass through the first mass analyzer and the precursor ions located within the mass window cannot pass through the first mass analyzer; c. feeding the precursor ions passing through the first mass analyzer into a collision cell for collisional dissociation, to generate product ions; d. feeding the product ions into a second mass analyzer for mass analysis and recording a spectrum; and e. repeating Steps b-d. Each time when Step b is repeatedly performed, the selected mass window does not overlap with all the mass windows previously selected. After all the mass windows in a mass range are selected, the repetition is stopped.
