  • Mass spectrometer using an accelerating traveling wave
    Patent number: 8309915
    Abstract: A mass spectrogram employs a set of controllable electrodes to produce a time varying axially inhomogenous electric field and enhance separation of charged particles by exposing the charged particles to different electric field strengths based on their spatial positions. The fields may be tailored to provide a traveling wave that expands portions of a spectrographic plot of the particles and/or to provide focusing or other effects.
    Type: Grant
