摘要： This invention provides a method for rapidly detecting volatile substances of very high concern (SVHCs) in a textile. Based on the ion mobility spectrometry technique, this method may achieve rapid detection of 11 kinds of volatile SVHCs within 1-6 minutes, respectively, by means of direct introduction of textile samples or in combination with an efficient and convenient solvent extraction pretreatment step. The detection limit is less than 100ppm, which absolutely satisfies the mass fraction limit of 1000ppm prescribed in REACH Regulation of the European Union. This method may greatly shorten detection periods of these volatile organics and enable the possibility to realize online detection for these substances.

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： Embodiments of the present invention provide an air dryer for an ion mobility spectrometer, comprising a heating element used to heat a thermal conduction device, thereby heating the desiccant. Embodiments of the present invention further provide a regeneration method, by which the operation mode of the ion mobility spectrometer may be switched, so that during a non-working time of the ion mobility spectrometer, the desiccant is heated and thereby regenerated. With the present invention, the desiccant is avoided from being regularly replaced, thereby improving the performance and increasing the service life of the dryer. Regeneration of thedesiccant is performed by making full use of the non-working time of the ion mobility spectrometerwithout affecting normal operation of instrument.
