摘要： 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.

摘要： Disclosed is an ion source comprising a plate-shaped source body which has radioactivity on its both sides and allows positive and negative ions to penetrate through the source body. 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.
