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.

摘要： The present invention relates to a method of improving detection sensitivity of an ion mobility spectrometer, comprising: inserting a sample into a sample receiving device of the ion mobility spectrometer; triggering an operation of spectra acquisition through an optocoupler; when the number of the acquired spectra reaches the level required to contain enough information for accurate detection of explosives with relatively high vapor pressure, adding a dopant instantly to the ionization region by controlling the ON/OFF-state of an electromagnetic valve; when the number of the acquired spectra reaches the level required to contain enough information for accurate detection of explosives with relatively low vapor pressure, stopping the acquisition operation, and turning off the electromagnetic valve so as to stop adding the dopant to the ionization region; analyzing all of the acquired spectra to obtain the detection result. The addition time of the dopant is controlled such that the dopant can take effect on the detection of some explosives with relatively low vapor pressure while the explosives which can be detected with higher sensitivity when no dopant is added can be analyzed in the case that the dopant concentration is very low, thereby achieving the optimal detection performance of the apparatus by taking account of its response to various explosives.

摘要： A hand-held sampling apparatus used for an ion mobility spectrometer and method of obtaining a sample are provided to prevent deformation of sampling wipes when detecting explosives and drugs. The apparatus has a body comprising a handle in the rear portion and a wiping sampling mechanism in the front portion, with a wiping surface located on its underside. The sampling wipe can be in full contact with the surface of the object during wiping to improve wiping efficiency. Correspondingly, a smaller sample inlet port can be disposed on the analyzer so as to save a large amount of sampling wipes. and meanwhile avoid sampling wipes from deformation and folds hard to restore, thereby ensuring subsequent sample insertion operation, enhancing the efficiency of both sample collection and sample injection and improving the detection performance for the analytes to be detected. The method of using said sampling device according to the present invention comprises the following steps: attaching a sampling wipe to the swiping surface; fixing the front end portion of the sampling wipe by using the front holder, and fixing the rear end portion of the sampling wipe by using the rear holder. The method of the present invention is simple and convenient.
