摘要：

Modeling of a Micro Ion Mobility Spectrometer (mu IMS) is developed for sensing acetone (Ac) and dimethyl methylphosphonate (DMMP) for Security Applications. In mu IMS target ions are discriminated by the application of the proper separation voltages to the electrodes of the system. Ions are modeled using literature values for their main parameters: K(0), alpha(2) and alpha(4). By modeling, optimum voltages for achieving the proper sensitivity have been obtained.
