Abstract: The present disclosure provides an electrode ring for an ion mobility spectrometer, an ion transfer tube and an ion mobility spectrometer. Wherein, the electrode ring has an outer edge thickness larger than its inner edge thickness in an axial direction. Through the present disclosure, in the structure of the electrode ring, the uniformity of the electric filed inside the transfer tube can be significantly improved. In the present disclosure, the smooth ion transfer zone inside the transfer tube can be enlarged. The ion transfer tube formed of electrode rings each having an inner edge thickness the same as the outer edge thickness in the axial direction apparently has poorer uniformity of electrode field than the ion transfer tube formed of electrode rings each having the same outer edge thickness but an inner edger thickness smaller than the outer edge thickness in the axial direction.

Abstract: The present disclosure discloses a continuous operable gas purification device in an ion mobility spectrometer including a housing provided with a cylinder cavity; a dry gas supply unit; a rotating barrier arranged in a radial direction of the cylinder cavity to divide it into a baking cavity and a working cavity; and a rotating mechanism. The housing is provided with a dry gas inlet and a dry gas outlet, which are communicated with the baking cavity, and a sample gas inlet and a sample gas outlet, which are communicated with the working cavity. The dry gas supply unit is connected with the dry gas inlet for a dry gas supply to the dry gas inlet. The baking cavity is provided with a heating unit correspondingly. The rotating mechanism is provided at a central position of the cylinder cavity and connected with the rotating barrier for rotating it at intervals.
