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.

摘要： An ion mobility spectrometer and method thereof are disclosed. The ion mobility spectrometer comprises an electrode and an ion source arranged adjacent to the electrode, wherein the ion mobility spectrometer further comprises: a single or a group of focusing guide electrodes arranged on the side of the ion source far away from the electrode and shaped as a funnel to output ions from the ion source; and a storage section arranged on the ion-outputting side of the focusing guide electrode for storing ions generated from the ion source. With the scheme of separating the ion source and the storage region, the present invention can facilitate exchange of different ion sources, so that a source can be replaced with another different source without any change in the subsequent configuration. The storage section can be made very thin in the direction of ion movement, its diameter can be very large, and the internal electric field is almost zero. Thus, it is possible to collect a huge amount of ions with a very small cluster thickness and a directional velocity of almost zero, leading to reduction in spread of ion mobility spectrum and increase in resolution.
