  • System for collection of data and identification of unknown ion species in an electric field
    Patent number: 7045776
    Abstract: An apparatus for identification of chemical species by measurement of mobility as a function of high electric field and for generating unique compound-dependent signatures based on ion mobility at a plurality of peak RF voltages for a given compensation. The resulting detection data is compared against a library of data in order to identify a detected chemical species.
    Type: Grant

  • Capacitive discharge plasma ion source
    Publication number: 20030070913
    Abstract: In a system for chemical analysis, an RF-driven plasma ionization device including a pair of spaced-apart and plasma-isolated electrodes, the electrodes are connected to a power source wherein the electrodes act as plates of a capacitor of a resonant circuit, the gas electrically discharges and creates a plasma of both positive and negative ions, and the voltage is applied as a continuous alternating waveform or as a series of pulses, such as a packet waveform.
