  • Patent number: 11031218
    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.

  • Patent number: 10192728
    Abstract: The disclosure relates to a mass spectrometer and a method applied thereby for reducing ion loss and succeeding stage vacuum load. The mass spectrometer includes an ion source connected via vacuum interfaces, a vacuum chamber and a succeeding stage device; wherein a tubular lens is arranged above a Mach disc formed by a gas flow carrying ions at the vacuum interfaces, so that an ion transfer path is restrained and the ions scattering with the gas flow is reduced. In comparison to a sole reliance on a radio-frequency voltage for focusing ions, the efficiency of ion capture in a jet region is improved by using an aerodynamic lens; and the desolvation efficiency of electrically charged droplets is also improved, thereby further improving the sensitivity of the mass spectrometer. Meanwhile the tubular aerodynamic lens is simple in structure and small in size.
