    • Multiplex data acquisition modes for ion mobility-mass spectrometry 
      Mclean, John A.; Russell, David H.; Egan, Thomas F.; Ugarov, Michael V.; Schultz, Albert J. (United States. Patent and Trademark Office; Texas A&M University. Libraries, 2010-06-29)
      A method and apparatus for multiplexed data acquisition for gas-phase ion mobility coupled with mass spectrometry is described. Ion packets are injected into an ion mobility drift chamber at a rate faster than the ion ...
    • Periodic field focusing ion mobility spectrometer 
      Gillig, Kent J.; Russell, David H. (United States. Patent and Trademark Office; Texas A&M University. Libraries, 2003-10-28)
      This invention is generally in the field of improved ion mobility spectrometry. The improvement lies in the use of periodic focusing electric fields that minimize the spatial spread of the migrating ions by keeping them ...
