Patricia H. Cormia has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Ion sampling for APPI mass spectrometry
    Patent number: 7309859
    Abstract: An atmospheric pressure ion source, e.g. for a mass spectrometer, that produces ions by atmospheric pressure photoionization (APPI). It includes a vaporizer, a photon source for photoionizing vapor molecules upon exit from the vaporizer, a passageway for transporting ions to, for example, a mass spectrometer system, and a means for directing the ions into the passageway. The center axis of the vaporizer and the center axis of the passageway form an angle that may be about 90 degrees. Included in the invention is a method for creating ions by atmospheric pressure photoionization along an axis and directing them into a passageway oriented at an angle to that axis.
    Type: Grant

  • Multimode ionization mode separator
    Patent number: 7223968
    Abstract: A multimode ionization source includes an electrospray ionization source for providing a charged aerosol, an atmospheric pressure ionization source downstream from the electrospray ionization source for further ionizing said charged aerosol, and a mode separator, or mask, situated so as to separate a portion of the charged aerosol and prevent the portion from being exposed to the atmospheric pressure ionization source.
