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.
摘要翻译：公开了一种痕迹检测器。痕迹检测器包括：限定解吸区域的解吸腔室，解吸腔室具有壳体。壳体具有用于将待检测物质引入解吸室的样品进料口和用于排出从解吸室引出样品的气体的气体排出口。控制器用于控制微量检测器，使得微量检测器的预浓缩过程中，样品进料口和排气口与解吸室流体连通，从而连续进料和收集样品。采用上述方式，可以在样品进料过程和气体预浓缩过程中由痕量检测器执行数据收集，处理和分析过程。无论气体中待检测物质处于高浓度状态还是低浓度状态，痕迹检测器都具有良好的检测时间段，并且痕迹检测器可以长时间连续采样，从而提高被捕获物质的量与待检测气体中夹带的物质的量和累积捕获物质的量，减少检测不到该物质的可能性以及增加检测灵敏度。另外，在气体预浓缩过程中检测器的检测效率增加。

摘要： An electrode ring (1) used for an ion mobility spectrometer, an ion migration tube and an ion mobility spectrometer, wherein the outer edge thickness of the electrode ring (1) is greater than the inner edge thickness thereof in an axial direction. The structure of the electrode ring (1) is changed from the case where the inner edge thickness is equal to the outer edge thickness in the axial direction into the case where the inner edge thickness is less than the outer edge thickness in the axial direction, which significantly improves the electric field uniformity inside the migration tube. By means of the structure of the electrode ring (1) with the outer edge thickness being greater than the inner edge thickness in the axial direction, a smooth ion migration region inside the migration tube is expanded. The electric field uniformity of an ion migration tube composed of the electrode ring (1) with the inner edge thickness being equal to the outer edge thickness in the axial direction is significantly worse than that of an ion migration tube composed of the electrode ring (1), having the same outer edge thickness, with the inner edge thickness being less than the outer edge thickness in the axial direction.

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.
