Title: Ion trapping and separation using potential wells

Journal Article ·
OSTI ID:750191

A new mode of operation for an ion mobility spectrometer (IMS) has been demonstrated that uses potential wells to trap and separate ions by their mobility. This mode of operation has been made feasible by the improvements in personal computers that now allow real-time control of the potentials on ring electrodes in the IMS drift tube. This mode of operation does not require a shutter grid and allows the accumulation of ions in the potential well to enhance the ion signal. Loss of ions from the potential well is controlled by the radial electric fields required by Gauss's law.
