摘要： A method of operating an ion trap mass spectrometer comprises generating a three dimensional trapping field with DC and/or RF voltages applied to an ion trap structure to trap ions over a predetermined mass-to-charge range, scanning the DC and/or RF voltages to sequentially eject ions over said range and simultaneously applying a supplementary AC voltage to generate an AC field to more effectively eject said ions.

摘要： An ion guide is disclosed wherein an axial DC voltage barrier 103 is created at the exit of the ion guide. A primary RF voltage is applied to the electrodes in order to confine ions radially within the ion guide. A supplemental RF voltage is also applied to the electrodes. The supplemental RF voltage has a greater axial repeat length than that of the primary RF voltage. The amplitude of the supplemental RF voltage is increased with time causing ions to become unstable and gain sufficient axial kinetic energy such that the ions overcome the axial DC voltage barrier. Ions emerge axially from the ion guide in mass to charge ratio order.

摘要： A mass spectrometry method in which a combined field (comprising a trapping field and supplemental field) is established and at least one parameter of the combined field is changed to excite ions trapped in the combined field sequentially (such as for detection). The supplemental field is a periodically varying field having an off-resonance frequency, in the sense that the supplemental field frequency nearly matches (but differs from) a frequency of motion of an ion stably trapped by the trapping field alone. Sequential ion excitation in accordance with the invention can rapidly excite each ion to a degree sufficient for a desired purpose but insufficient for ejection from the trap. The amplitude of the supplemental field is kept sufficiently high to excite ions (via an off-resonance excitation mechanism) before they undergo resonant excitation.

摘要： A method of using a quadrupole ion trap mass spectrometer for high resolution mass spectroscopy is disclosed. High resolution of a mass spectrum of a desired species is achieved by first using a slow scanning rate and by first ridding the trap of unwanted ions. Accurate mass calibration is achieved by using a reference compound of known mass and using a second supplemental AC dipole voltage to eject the reference ions at nearly the same time as the sample ions of interest are ejected from the trap. This eliminates the need to scan the trap between the masses of the sample and reference ions. Space charge in the trap is held constant, thereby eliminating a major source of mass axis instability, by using the results of one scan to control the ionization time during the next scan. Preferably, during ionization a broadband supplemental dipole voltage is applied to the ion trap to rid it of unwanted ions. During a portion of the ionization time the broadband signal is constructed to retain only sample ions in the ion trap, and during the remainder of the ionization time the broadband signal is constructed to retain both sample and reference ions in the ion trap. By adjusting the relative lengths of the two portions of the ionization time the total space charge in the ion trap can be held constant notwithstanding variations in sample ion concentration.

摘要： A mass spectrometer system and a method of operating a mass spectrometer having an elongated rod set, the rod set having an entrance end, an exit end, a plurality of rods and a longitudinal axis, involving (a) admitting ions into the entrance end of the rod set; (b) producing an RF field between the plurality of rods to radially confine the ions in the rod set; (c) providing a static axial electric field within the rod set; and (d) separating the ions into a first group of ions and a second group of ions by providing an oscillating axial electric field within the rod set to counteract the static axial electric field, wherein the oscillating axial electric field varies along the longitudinal axis of the rod set.
