  • Chemical detection system and method using a capacitive trans impedance amplifier
    Patent number: 8207492
    Abstract: The exemplary embodiments provide a method, system, and device for identifying chemical species in a sample. According to one embodiment, the method, system, and device may include introducing a sample gas into a differential ion mobility device, ionizing at least a portion of the sample gas to generate at least one ion species, filtering the at least one ion species between a pair of filter electrodes, generating a detection signal in response to the at least one ion species depositing a charge on a collector electrode, and detecting a spectral peak associated with the at least one ion species.
    Type: Grant
    Filed: January 16, 2009
    Date of Patent: June 26, 2012
    Assignee: Chemring Detection Systems, Inc.
    Inventors: Matthew Todd Griffin, John Michael Alfred Petinarides, Paul Joseph Rauch, Jerome Paul Dahl, Robert Francis McAtee
