There is provided an ion-mobility spectrometer. This apparatus includes the following configuration components: An ion source for generating first ions, a first drift unit for separating the first ions by flight drift times, an ion dissociation unit for generating second ions by dissociating the first ions separated, and a second drift unit for separating the second ions by flight drift times. Moreover, the first drift unit, the ion dissociation unit, and the second drift unit are located inside a chamber whose pressure is set at 10 mTorr or higher. This apparatus allows execution of low-cost and high-resolving-power ion separation and detection.
