Abstract: An ion mobility separation device includes: an ion source that generates an ion; a pair of flat-plate electrodes having an introduction opening and a discharge opening for the ion generated by the ion source; a pump for causing the ion introduced via the introduction opening of the pair of flat-plate electrodes to travel toward the discharge opening; a voltage control unit that applies an asymmetric time-varying voltage and a direct-current voltage to the pair of flat-plate electrodes; a plurality of detectors disposed in a direction orthogonal to both an ion travel direction due to the pump and an applied direction of the asymmetric time-varying voltage; and a signal processing unit that processes a signal detected by the plurality of detectors. The voltage control unit performs a total transmission measurement involving application of the voltages to the pair of flat-plate electrodes so as to generate equal fields at least at two different points in the direction orthogonal to both the ion travel direction due to the pump and the applied direction of the asymmetric time-varying voltage. Compared to conventional technology, both high accuracy and high throughput are achieved in an asymmetric field application-type ion mobility separation device.
