Abstract: An apparatus and a method for detecting hazardous substances on a surface of an object are provided. The apparatus for detecting hazardous substances on a surface of an object comprises: a conveyer belt (1) for conveying an object, a capture device (6) provided to match the conveyer belt (1), wherein the capture device (6) may automatically capture a substance adsorbed on the surface of the object when the object is being conveyed by the conveyer belt (1), and a detection module (3) for automatically detecting the substance captured by the capture device (6). The present invention also provides a method for detecting a substance adsorbed on the surface of an object by utilizing the detection apparatus and a method for detecting whether the detected substance is hazardous or not. The detection technique of the present invention enables quick detection for poisons, explosives, and other substance particles attached on the surfaces of cargos and mails.

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.
