United on-line detector for explosive and poison and application thereof

Abstract

The invention discloses a table type on-line detector for X-ray scanning initial separation / ion migration spectrum explosive. The X-ray detector adopts a dual-view dual-energy security detector, and uses X-rays of two angles and two energies to scan so as to improve the definition of images and benefit the identification of dangerous goods. The ion migration spectrum adopts a composite array type ion migration spectrum instrument which combines at least two ionization modes of positive and negative ion detection modes are combined, broadens the compound category detected by the ion migrationspectrum and greatly improve the quick identification and resolving capacities of the ion migration spectrum on samples at the same time. The X-ray detector capable of quickly scanning luggage and the ion migration spectrum capable of accurately detecting suspected objects are combined so as to shorten the luggage detection speed and improve the detection accuracy of the dangerous goods.

Description

technical field [0001] The invention belongs to a security inspection analyzer, specifically a desktop X-ray scanning primary selection / ion mobility spectrum combined online detector for explosives (drugs). The device uses X-ray perspective scanning to screen suspicious items, and ion mobility spectroscopy accurately measures phase Combined with a quick security check of items. Background technique [0002] Over the years, drug smuggling and bombing terrorist activities have always been the focus of customs, aviation, and transportation to combat crime and security. As the criminal means of criminals become more and more advanced, the traditional detection means are powerless. How to improve the identification accuracy and quickly and accurately detect hidden drugs or explosives in high-speed crowds and cargo groups has become a very urgent and unresolved technical problem. The development of forms has prompted countries all over the world to explore more advanced security...

Problems solved by technology

In order to solve the peak overlap caused by this low resolution, we have recently developed a VUV photoionization, radioactive 63 Ni and tip discharge (CD) ion mobility spectrometer for common organic compounds such as formaldehyde, acetaldehyde, acetone and butanone, benzene series, H 2 When measuring compounds such as S and HCl, it is found that the same compound can produce different ions in different ionization modes, corresponding to different mobility; the positive and negative ion mobility spectra are also very different
