Abstract:
A first shutter gate is disposed at an entrance of a drift region, and a second shutter gate is disposed on the downstream side in an ion-drifting direction. In a high-resolution measurement mode, a controller ( 9 ) controls voltage generators to open the second shutter gate to collect ions into a pulsed form at the first shutter gate. In this mode, the controller controls the voltage generators to open the first shutter gate to collect ions into a pulsed form at the second shutter gate. In a zoom-in measurement mode where ions within a specified range of ion mobility are measured with high resolving power, the controller controls the voltage generators to open the first shutter gate for a short period of time, and then to open the second shutter gate for a short period of time after a lapse of a predetermined time period.

Claim (Index 1):
An ion mobility spectrometer in which ions in a packet-like form are introduced into and made to drifted through a drift region in which an electric field is formed to separate the ions according to their ion mobilities, the ion mobility spectrometer comprising:\n a) a first shutter gate disposed at an entrance of the drift region; b) a second shutter gate disposed on a downstream side of the first shutter gate in a drifting direction in the drift region; c) a voltage generator for applying predetermined voltages respectively to the first and second shutter gates; and d) a controller for controlling the voltage generator so as to apply voltages to the first shutter gate and the second shutter gate so that ions are made to pass through the first shutter gate in a pulsed form and to directly pass through the second shutter gate in a first measurement mode, while ions are made to directly pass through the first shutter gate and to pass through the second shutter gate in a pulsed form in a second measurement mode.
