In Eiceman and Karpas’s book Ion Mobility Spectroscopy (2005), they define Ion Mobility Spectroscopy (IMS) as "the principles, methods, and instrumentation for characterizing chemical substances on the basis of velocity of gas-phase ions in an electric field."

The production of the electric field and signal processing components is relatively inexpensive compared to other analytical techniques. The convenience of use and high speed of processing has made IMS a technology of choice for a number of field applications.  The use of COMSOL Multiphysics to model the system is leading to a deeper understanding of how the variables affect the performance of the system.
