  • Continuous flow mobility classifier interface with mass spectrometer
    Patent number: 9177774
    Abstract: A continuous flow mobility classifier provide the ability to perform two-dimensional separation in mass spectrometry. An ionization system is used to ionize a sample. A differential mobility analyzer (DMA) (e.g., a nano-radial DMA) is coupled to the ionization system and to a mass spectrometer. The nano-RDMA is configured to separate the ionized sample by mobility for subsequent mass analysis by the mass spectrometer.
    Type: Grant
    Filed: January 18, 2011
    Date of Patent: November 3, 2015
    Assignee: California Institute of Technology
    Inventors: Nicholas Brunelli, Konstantinos P. Giapis, Richard C. Flagan, Jesse L. Beauchamp, Evan Neidholdt
