  • Publication number: 20070023676
    Abstract: The present invention provides an apparatus and method for use with a mass spectrometry system. The invention provides an ion source for providing radiative heating to an ionization region. The ion source includes a nanospray ionization device for producing ions and a conduit adjacent to the ionization device for receiving ions from the ionization device. The conduit includes a conductive material for providing indirect radiative heating to the ionization region. Direct radiative heating may also be provided using a heater in the conduit. The ion source may be used separately or in conjunction with the mass spectrometry system. When used in conjunction with a mass spectrometry system a detector may also be employed down stream from the device. A method for desolvating an analyte using the device is also disclosed.

  • Patent number: 7135689
    Abstract: The present invention relates to an apparatus and method for use with a mass spectrometer. The ion enhancement system of the present invention is used to direct a heated gas toward ions produced by a matrix based ion source and detected by a detector. The ion enhancement system is interposed between the ion source and the detector. The analyte ions that contact the heated gas are enhanced and an increased number of ions are more easily detected by a detector. The method of the invention comprises producing analyte ions from a matrix based ion source, enhancing the analyte ions with an ion enhancement system and detecting the enhanced analyte ions with a detector.
