The ion gate includes an ion source, a first gate electrode placed on one side of the ion source, a second gate electrode placed on the other side of the ion source, a third gate electrode placed on the side of the first gate electrode away from the ion source, a fourth gate electrode placed on the side of the second gate electrode away from the ion source, wherein during the ion storage, the potential at the position on the tube axis of the ion gate corresponding to the first gate electrode is different from the potentials at the positions on the tube axis corresponding to the ion source and the third gate electrode, and the potential at the position on the tube axis corresponding to the second gate electrode is different from the potentials at the positions on the tube axis corresponding to the ion source and the fourth gate electrode. According to the present invention, after sample gas enters the ion gates, charge exchange with reaction ions occurs between the first gate electrode and the second electrode, and positive and negative ions are continuously stored into the storage regions for the positive and negative ions. This leads to an improvement of utility rate of ions. Then, the ions are educed in a step-wise manner from the storage regions for the positive and negative ions by a simple control of a combination of the electrodes.

Abstract: Disclosed is an electrode structure for a drift tube in IMS comprising a ring electrode, for each of two surfaces of the ring electrode, at least a part adjacent to the inner radius is formed into a cone, and the angles formed between the cones and the axis of the ring electrode are different from each other. The electrode structure of the present invention can alleviate, even eliminate, the accumulation of space charges in the drift tube. Such structure is particularly suitable when the electric field in the drift tube is low in strength or a great number of ions pass through. Meanwhile, the structure allows a significant decrease in the size of the outer radius of the electrode, while the inner radius remains constant. In this way, it is possible to effectively reduce the outline size of the drift tube and thus make the IMS compact.

The present invention gives beneficial effects. First, the ion source structure can improve the ionization efficiency of sample molecules, and the generated sample ions have a centralized distribution within a flat space on both sides of the source body. Such distribution of ion cloud facilitates to improve the IMS sensitivity. Meanwhile, the source body of the present invention has a transmittance in itself. Thus, positive and negative ions generated on both sides of the source body can penetrate through the source body and be separated to the both sides of the source body. In this way, it is possible to improve the utilization efficiency of ions.
