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 detection apparatus and method for an ion migration spectrum include acquiring an ion migration spectrum of pure carrier gas and an ion migration spectrum of carrier gas containing a test substance sample and performing differential process on the ion migration spectrum of the pure carrier gas and the ion migration spectrum of the carrier gas containing the test substance sample to acquire a differential spectrum. The value of a characteristic peak of the differential spectrum represents properties of the sample of substances. The method avoids interferences on the migration spectrum from interference sources of the apparatus itself, thereby improving detection sensitivity and accuracy of the ion migration spectrum, and migration spectrum shift caused by variations in the environmental conditions can be found and corrected through the differential process on the migration spectrum of the pure carrier gas, thereby achieving self-stableness and self-correction of the ion migration spectrometer.

According to the present invention, after sample gas enters the ion gates, charge exchange with reaction ions occurs between the first gate electrode and the second electrode, and positive and negative ions are continuously stored into the storage regions for the positive and negative ions. This leads to an improvement of utility rate of ions. Then, the ions are educed in a step-wise manner from the storage regions for the positive and negative ions by a simple control of a combination of the electrodes.
