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.

Abstract: A cryostat includes a room temperature vessel, a low temperature vessel, and a refrigeration mechanism. The room temperature vessel includes a room temperature tank, an outer neck tube and a sealing head. The low temperature vessel includes a low temperature tank, an inner neck tube and a liquefaction chamber. The liquefaction chamber corresponds to the first opening and passes through the first opening. The refrigeration mechanism includes a device panel and a refrigeration device. The device panel is disposed on the sealing head. The refrigeration device includes a body and a cold finger. The body is disposed at the device panel. The cold finger is connected with the body and extends into the liquefaction chamber.
