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： 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： The present invention discloses a sample analyzer comprising a heater and a sample feeding carrier, wherein the heater and the sample feeding carrier are integrally formed, such that the positional relation between the sample feeding carrier and the heater is fixed. Compared with the prior art, since the heater and the sample feeding carrier of present invention is formed integrally, the positional relation between the sample feeding carrier and the heater is fixed, accordingly, the consistency in heating-up of the sample is enhanced. Moreover, because the sample feeding carrier and the heater are made of low capacity material, the change of the temperature is rapid during the heating process, as a consequence, the analyzer consumes less power and could achieve a rapid temperature control.
