摘要： A sample processing system and a sample processing method for a trace detector are disclosed. The system comprises a sampling substrate for collecting a substance or substances from the surface of an object to be tested by contacting the sampling substrate with the surface of the object, and a trace detector. The trace detector includes a sample feeding device provided with a sample feeding part. The substance collected by the sampling substrate can be transferred to a surface of the sample feeding part so that the substance transferred to the surface of the sample feeding part can be detected. With the configuration of some embodiments of the present invention, a sampling substrate made of chemical fiber is used to collect a sample from the surface of an object to be tested by contacting the sampling substrate with the surface of the object to be tested. The sample collected by the sampling substrate is mechanically transferred to a metal film or mesh of the sample feeding device of the trace detector. Then, the metal film or mesh of the sample feeding device is heated to vaporize the sample and to release the sample vapor into the trace detector. Therefore, the efficiency of sample collection and desorption processes can be improved. In addition, the direct heating of a sampling substrate can be avoided so as to decrease the interference of the sampling substrate with trace detection.

摘要： A trace detector is disclosed. The trace detector comprises: a desorption chamber defining a desorption region, and the desorption chamber has a housing. The housing has a sample feeding port for introducing a substance to be detected into the desorption chamber and a gas discharge port for discharging gas entraining the sample from the desorption chamber. A controller is used for controlling the trace detector in such a manner that the sample feeding port and the gas discharge port are in fluid communication with the desorption chamber during pre-concentration process of the trace detector, thereby continuously feeding and collecting the sample. With the above manner, data collecting, processing and analyzing processes may be performed by the trace detector throughout the sample feeding process and the gas pre-concentrating process. The trace detector has an excellent detecting period of time whether the substance to be detected in the gas is in a high concentration state or a low concentration state, and the trace detector can perform continuous sampling for a long time, thereby improving a ratio of the amount of trapped substance to the amount of the substance entrained in the gas to be detected and the amount of the cumulated trapped substance, decreasing the probability of failing to detect the substance, and increasing detection sensitivity. In addition, the detection efficiency of the detector is increased during the gas pre-concentration process.

摘要： Disclosed is an ion source comprising a plate-shaped source body which has radioactivity on its both sides and allows positive and negative ions to penetrate through the source body. The present invention gives beneficial effects. First, the ion source structure can improve the ionization efficiency of sample molecules, and the generated sample ions have a centralized distribution within a flat space on both sides of the source body. Such distribution of ion cloud facilitates to improve the IMS sensitivity. Meanwhile, the source body of the present invention has a transmittance in itself. Thus, positive and negative ions generated on both sides of the source body can penetrate through the source body and be separated to the both sides of the source body. In this way, it is possible to improve the utilization efficiency of ions.

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.
