The present invention relates to a device for separation and characterization of gas-phase ions. The device incorporates an ion source a field asymmetric , waveform ion mobility spectrometry (FAIMS) analyzer an ion mobility , spectrometry (IMS) drift tube and an ion detector. In one aspect of the invention, FAIMS operating voltages are electrically floated on top of the IMS drift voltage. In the other aspect, the FAIMS/IMS interface is implemented employing an electrodynamics ion funnel including in particular an hourglass , ion funnel. The present invention improves the efficiency (peak capacity) and sensitivity of gas-phase separations; the online FAIMS/IMS coupling creates a …
