  • Publication number: 20070284519
    Abstract: A cross-flow ion mobility analyzer (CIMA) that includes a component of gas flow that opposes an electric field that is established within a channel, wherein ions are carried through the channel, wherein ions of a specific mobility are trapped by the opposing electric field and flow field within the channel and are detected when the ions reach the end of the channel, wherein a detector at the end of the channel sees a continuous stream of mobility-selected ions, and wherein different ions are selected by modifying the electric field and/or the velocity of the flow field.

  • Publication number: 20070246650
    Abstract: A virtual ion trap that uses electric focusing fields instead of machined metal electrodes that normally surround the trapping volume, wherein two opposing surfaces include a plurality of uniquely designed and coated electrodes, and wherein the electrodes can be disposed on the two opposing surfaces using plating techniques that enable much higher tolerances to be met than existing machining techniques.

  • Patent number: 7075064
    Abstract: A system and method are provided of extracting spectra from data produced by temporally indexed spectral scans from a spectrometer and spectrometer. The method includes the operation of receiving a data matrix from the spectrometer. The noise can then be removed from the data matrix. A further operation is identifying spectra of interest in the data matrix based on information content. In addition, a reduction transformation can be applied to the data matrix based upon the spectra of interest based upon the denizen transformation for the purpose of extracting the spectra of interest from the data matrix.

  • Publication number: 20050165560
    Abstract: The present invention provides methods for high throughput analysis of analytes in complex mixtures for unresolved chromatographic peaks including specific embodiment for summing intensities for each mass transition of interest over a selected chromatographic peak (50) to generate a signal corresponding to total intensity for each transition (55, 60). The intensities are deconvoluted into intensities of individual analytes (65, 70), based on branching ratios acquired from authentic standards, and a comparison to calibration curve is performed to obtain a quantitative concentration measurement of a particular analyte in a sample.

  • Publication number: 20050029445
    Abstract: A single set of electrodes, wherein different electrical potentials are applied to the single set of electrodes at different times in order to perform both ion mobility-based spectrometry and mass spectrometry (MS) on a sample of ions, wherein the ions are processed by performing ion mobility-based spectrometry and mass spectrometry in any sequence, any number of times, and as isolated or superposed procedures in order to trap, separate, fragment, and/or analyze charged particles and charged particles derived from atoms, molecules, particles, sub-atomic particles and ions.

  • Patent number: 5777326
    Abstract: A method and apparatus for extending the dynamic range of a data acquisition device. A system of multiple anode detectors are used to increase the dynamic range of a time-to-digital converter. Multiple anodes enable the system to determine characteristics of a signal without distortion of the signal which normally occurs with large signals, or obscuring of the signal by noise which normally occurs with small signals. The data from the multi-anode system can be processed so that the total number of impacts of the signal on the multiple anodes are summed during selectable time frames and made available as multiple bit words. This approach combines virtually all the advantages of a transient digitizer with the advantages of a time to digital converter when acquiring signals from pulse-based detectors such as microchannel plates.
