摘要： The present invention relates to an apparatus and method for producing ions. The apparatus may be used separately as an ion source or in combination with a mass spectrometry system. The ion source of the present invention provides an ionization device for producing ions, a substrate for capturing, storing and releasing ions produced by the ionization device, a conductive material in contact with the substrate for receiving an electrical pulse, and a voltage source electrically connected to the conductive material for applying an electrical pulse to the conductive material and substrate to release the ions captured by the substrate. Also disclosed is a method for storing and releasing ions using the disclosed apparatus.

摘要： The present invention provides an apparatus and method for use with a mass spectrometer. The invention provides a mass spectrometer system for non-pneumatic ion production, including a non-pneumatic nanospray ionization source. The nanospray ionization source has a first non-pneumatic ion spray emitter for producing ions; a conduit adjacent to the ion spray emitter, the conduit having an aperture designed for receiving ions from the ion spray emitter; a first electrode for directing the ions from the ion spray emitter toward the aperture of the capillary; and a conduit electrode for directing ions into the conduit; and detector down stream from the capillary for detecting ions produced by the non-pneumatic nanospray ionization source.
The invention also provides a non-pneumatic nanospray ionization source, comprising a first non-pneumatic ion spray emitter for producing ions; a conduit adjacent to the ion spray emitter, the conduit having an aperture designed for receiving ions from the ion spray emitter; a first electrode for directing ions from the ion spray emitter toward the aperture of the conduit and a conduit electrode for directing ions into the conduit.
Also disclosed is a method for producing ions using a nanospray ionization source.
