    摘要: A sample feeding device for a trace detector is disclosed. 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. With the above configuration of the present invention, for example, the sensitivity of the detector can be increased by improving the permeation ratio of the 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: A drift tube structure for ion mobility spectrometer is disclosed comprising electrode sheets and insulation parts arranged in alternation, with each electrode sheet being a mesh metal sheet having a radian or taper portion which is convexly curved toward an ion input. Further, the radian or taper portion of the electrode sheet has meshes of higher transparency. With the above structure of the present invention, an electric field having a periphery of uniform focusing center can be formed in the migration zone. The circular ring configuration of the electric field periphery can shield the migration electric field from any influence of external electric fields. The electrodes are each meshlike and have a circular hole at the center, thus they can focus and collect as many as possible ions that do not move along the central axis, and those ions moving along the central axis can pass through the electrodes transparently.
