A micro Planar Ion Mobility Spectrometer (P-FAIMS) has been simulated using multiphysics software. In P-FAIMS target ions are discriminated by the application of the proper separation voltages to the electrodes of the system. Modelling of vapour phase ions of two compounds have been studied for different values of electric field amplitude to gas number density (E/N) ratio: a health risky volatile acetone Ac₂H⁺, ion, and a chemical warfare agent simulant DMMPH⁺ ion that emulates gas sarin. Results shows that simulations of ions behaviour in a P-FAIMS are possible with COMSOL and that the time and intensity at which ions are detected are in good agreement with experimental data found in the literature.
