  • Methods and systems for ion mobility and mass analysis
    Patent number: 11264227
    Abstract: An ion manipulation device and systems and methods for controlling the ion manipulation device. The ion manipulation device includes a pair of counter-facing surfaces and a plurality of electrodes arranged in one or more linear array on each of the counter-facing surfaces. At least one RF power source is coupled to the electrodes and configured to apply an RF potential to the electrodes to create an electric field that inhibits charged particles from approaching the counter-facing surfaces. At least one DC power source is coupled to the electrodes and configured to apply a DC potential to affect the movement of ions between the counter-facing surfaces in a direction parallel to the counter-facing surfaces. The DC potential and the RF potential are applied to the electrodes simultaneously.
