  • Method and apparatus for a nanoelectrosprayer for use in mass spectrometry
    Patent number: 6753521
    Abstract: The present invention provides a nanospray means and method for use in mass analysis instruments. Specifically, a nanospray assembly is composed in part of a base, union, retainer, and nanospray needle, and an entrance cap, first capillary section, and union. Adjustments to the position of the nanospray needle within this assembly are made independent of the remainder of the ion source. The nanospray assembly is integrated with the remainder of the source by joining the first capillary section (of the nanospray assembly) with a second capillary section which is fixed in the body of the source.

  • Ionization chamber for atmospheric pressure ionization mass spectrometry
    Publication number: 20030071209
    Abstract: The ionization chamber consists of a plurality of ports to accept multiple identical devices or varying devices. Ports may be arranged at various positions on the ionization chamber and at various angles with respect to the sampling orifice leading into the vacuum chamber of the mass spectrometer. A plurality of sprayers may operate in a time modulated manner and thereby the simultaneous multiplexed analysis of a multitude of samples is facilitated.

  • Device and method for forming ions
    Patent number: 6107626
    Abstract: A device and method for forming ions by inductive ionization is disclosed. The device is an ion source that includes a capacitor having a pair of electrodes separated by a dielectric material. The method of the invention uses the capacitor-based ion source to form positive and negative ions including multiply-charged ions.
