  • Pneumatic ion beam focusing in high-field asymmetric waveform ion mobility spectrometry (FAIMS)
    Patent number: 8049167
    Abstract: A FAIMS device for separating ions has a pair of electrodes for providing a compensation voltage and an asymmetric waveform that are separated and insulated where at least one porous spacer reside in the proximity of the analyzer region of the FAIMS cell. The porous spacers allow a focusing gas to flow into the analyzer region to provide pneumatic focusing of the ions traversing the analyzer region to improve the ion transmission.
    Type: Grant
    Filed: March 12, 2010
    Date of Patent: November 1, 2011
    Assignee: University of Florida Research Foundation, Inc.
