Abstract
An ion mobility analyzing apparatus includes: a drift tube having an internal space extending in a first direction; an ion chamber having an internal space extending in the first direction and connected to the drift tube; an ion gate installed at a boundary between the drift tube and the ion chamber and kept at a ground potential; an ion source supplying ions into the ion chamber; an ion detecting electrode arranged in the drift tube on a side opposite to the ion gate; a first voltage source supplying a first high voltage to the ion chamber; a second voltage source supplying a second high voltage, having an opposite polarity to that of the first high voltage, to the ion detecting electrode; and a signal transfer unit that detects a signal from the ion detecting electrode and transmits the signal to a data processing device operating with the ground potential.
