1. A system configured to permit switching of a cell between at least two modes comprising a collision mode and a reaction mode to select ions received by the cell, the system comprising:

  • a cell configured to receive a gas mixture comprising a binary gas mixture in the collision mode to pressurize the cell and configured to receive the same gas mixture comprising the binary gas mixture in the reaction mode to pressurize the cell; and

    a processor electrically coupled to the cell, the processor configured to provide a voltage to the pressurized cell comprising the gas mixture in the collision mode to facilitate the transmission of select ions with an energy greater than an energy barrier induced by the provided first voltage, wherein the processor is further configured to provide a second voltage to the pressurized cell comprising the gas mixture in the reaction mode to guide select ions into a mass filter fluidically coupled to the cell.
