The sample feeding device comprises: a sample feeding chamber disposed in the sample feeding device to desorb a sample from a sample feeding member; and a valve assembly configured to fluidly communicate the sample feeding chamber with a drift tube of the trace detector during feeding sample.

In addition, interior environment of the drift tube is isolated from exterior environment to avoid a drift region of the drift tube from being polluted. The important parameters, such as sensitivity, a position of a peak of a substance, a resolution, of the detector can be kept constant. As a result, operation reliability and consistency of the detector can be achieved.

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： An array-based ion storage system and method are disclosed. The system comprises: an ion generation section; and an ion storage section comprising a first end electrode coupled to the ion generation section and formed as having a plurality of holes, a second end electrode formed as having a plurality of holes, an intermediate electrode formed as having a plurality of holes, a first insulator formed in the shape of a ring and sandwiched between the first end electrode and the intermediate electrode to insulate them from each other, and a second insulator formed in the shape of a ring and sandwiched between the intermediate electrode and the second end electrode to insulate them from each other. With the present invention, the ion storage section can be made thinner to facilitate consistency in ion extraction and reduce the spread of ion mobility spectrum peak. In addition, the first and second insulators each have a big hole, and thus the ions cannot bump onto the insulation material at both sides at the time of ion vibration or thermal movement in the storage space. Therefore, charge transfer and accumulation at the insulator and the subsequent discharge will not occur, suppressing instability of storage and loss of ions.
