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.
