  • Publication number: 20220367163
    Abstract: A parallel multi-beam mass spectrometer includes an ion trap and a single multi-beam time-of-flight analyzer. The trap has a plurality of alternating electrodes configured to form a plurality of quadrupoles defining a surface of the trap, wherein at least two of the plurality of quadrupoles are configured as mass filters for selective ejection of concurrent parallel beams of ions from the trap in respective predetermined ion mass-to-charge windows. The single multi-beam time-of-flight analyzer has a position sensitive detector or a plurality of individual detectors for simultaneously receiving and analyzing the concurrent parallel beams of ions.

  • Publication number: 20070057178
    Abstract: A multi-device interface for use in mass spectrometry for interfacing one or more ion sources to one or more downstream devices. The multi-device interface comprises three or more multipole rod sets configured as either an input rod set or an output rod set depending on potentials applied to the multipole rod sets. The multipole rod sets configured as an input rod set are connectable to the one or more ion sources for receiving generated ions therefrom and sending the ions to at least one multipole rod set configured as an output multipole rod set. The output multipole rod sets are connectable to a downstream device for sending the generated ions thereto. At least two of the multipole rod sets are configured as input rod sets or at least two of the multipole rod sets are configured as output rod sets.

  • Publication number: 20070045533
    Abstract: A method for manipulating ions in an ion trap includes storing ions, spatially compressing, and ejecting selected ions according to mass-to-charge ratio. An ion trap includes an injection port, an arm having a first and a second end for confining and spatially compressing the ions, and an ejection port for ejecting the ions from the second end. The arm includes two pairs of opposing electrodes, which provide a quadrupole electric field potential at any cross-section of the ion trap. The distance between opposing electrodes and the cross-sectional area of the electrodes increases from the first to second end. The electrodes may be tapered cylindrical rods or of hyperbolic cross-section. Ions selected for ejection are spatially compressed into a region at the second (wider) end. The ion trap may include one arm, with either orthogonal or axial ejection, or two arms with a central insert for orthogonal ejection.

  • Patent number: 7109479
    Abstract: A system for determining the ratio of mass to charge of an ion including a pulsed ionizer, a high pressure co-linear ion guide/accelerator, and a mass analyzer. The pulsed ionizer generates intact analyte ions from a sample of matter to be analyzed. The high pressure co-linear ion guide/accelerator is interfaced with the ion source for receipt of the intact ions of the sample. The ion guide/accelerator simultaneously dampens and linearly accelerates the intact ions in the substantial absence of fragmentation of the ions to provide a substantially continuous beam of the intact ions for mass analysis. The mass analyzer is connected to the ion guide/accelerator for receipt of the beam of ions and determines the mass to charge ratio of the intact ions.

  • Patent number: 7012249
    Abstract: Disclosed is an apparatus for examining and inspecting at least one sample in order to determine characteristics of the sample having the a support for receiving a compact disc, the compact disc having deposited on a surface thereof at least one sample, inspection means for effecting a physical change in at least one sample, the inspection means positioned for registration with the surface of the compact disc bearing at least one sample; and a traversal mechanism adapted for reciprocating movement, to move the sample in and out of the path of the inspection means.

  • Publication number: 20050116158
    Abstract: A method and apparatus are provided for providing an ion transmission device or interface between an ion source and a spectrometer. The ion transmission device can include a multipole rod set and includes a damping gas, to damp spatial and energy spreads of ions generated by a pulsed ion source. The multipole rod set has the effect of guiding the ions along an ion path, so that they can be directed into the inlet of a mass spectrometer. The invention has particular application to MALDI (matrix-assisted laser desorption/ionization) ion sources, which produce a small supersonic jet of matrix molecules and ions, which is substantially non-directional, and can have ions travelling in all available directions from the source and having a wide range of energy spreads.
