    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 mobility spectrometer (IMS) detection method using dopants. The ion mobility spectrometer comprises a sample feeding device, a drift tube and a gas passage system communicated therewith. The gas passage system comprises a pump, a filtering device, a gas inlet and a gas outlet provided on the drift tube for providing clean gas used as the drift gas and the sample carrier gas. The detection method comprises: providing a sampling substrate for sample collection; combining the dopants with the sampling substrate; collecting the sample using the sampling substrate combined with the dopants; and introducing the sampling substrate that has collected the sample into the sample feeding port of the ion mobility spectrometer for detection. With this method, it is unnecessary to provide an independent dopant gas passage, thereby simplifying the structure of the instrument and meanwhile, making it easier and more accurate to control the amount of the dopants required for detection.
