  • Ion mobility spectrometer instrument and method of operation
    Patent number: 8513591
    Abstract: An ion mobility spectrometer instrument has a drift tube that is partitioned into a plurality of cascaded drift tube segments. A number of electric field activation sources may each be coupled to one or more of the plurality of drift tube segments. A control circuit is configured to control operation of the number of electric field activation sources in a manner that sequentially applies electric fields to the drift tube segments to allow only ions having a predefined ion mobility or range of ion mobilities to travel through the drift tube. The drift tube segments may define a linear drift tube or a closed drift tube with a continuous ion travel path. Techniques are disclosed for operating the ion mobility spectrometer to produce highly resolved ion mobility spectra.

  • Apparatus and methods for analyzing ions
    Patent number: 8362420
    Abstract: An apparatus (10) for separating Ions based on ion mobility includes a conduit (12) defining a closed path. The conduit is configured such that a uniform electric field is produced about the closed path upon application of a voltage causing ions within the conduit (12) to move about the closed path and to separate the ions based upon ion mobility. A method of separating a plurality of ions is also disclosed.

  • Ion mobility spectrometer instrument and method of operating same
    Patent number: 7838821
    Abstract: An ion mobility spectrometer instrument has a drift tube that is partitioned into a plurality of cascaded drift tube segments. A number of electric field activation sources may each be coupled to one or more of the plurality of drift tube segments. A control circuit is configured to control operation of the number of electric field activation sources in a manner that applies switched electric fields at a specified switching rate to the drift tube segments to thereby produce at the ion outlet only ions having a predefined ion mobility or range of ion mobilities.
