Explosive trace detection by ion mobility spectrometry for air cargo screening

  • This article describes the application of the ion mobility spectrometry (IMS) as a technical link in the screening within the airfreight transport chain. Air freight is of very important also for German foreign trade. Every year around 4.3 Mt of freight are loaded at German airports and transported by air planes. The average value of a transported metric ton freight was approximately 81,000 € in 2015. Nearly 50 percent of the total air freight is transported in passenger planes as belly freight. Measures are necessary to detect illegal, dangerous items such as weapons, ammunition or improvised explosive devices (IED) to protect against attacks on air traffic security. The aim is to increase security in air traffic and at the same time contemporary increasing or at least unchanged efficiency in the airfreight transport chain. IMS is a suitable instrumental technology for the trace detection of explosives (ETD) and their precursors orthogonal to radiological x-ray measurements onThis article describes the application of the ion mobility spectrometry (IMS) as a technical link in the screening within the airfreight transport chain.

The aim is to increase security in air traffic and at the same time contemporary increasing or at least unchanged efficiency in the airfreight transport chain. IMS is a suitable instrumental technology for the trace detection of explosives (ETD) and their precursors orthogonal to radiological x-ray measurements on suspicious freight within 30 seconds and per EU regulation 2015/1998, section 6.2. The ECAC* certified ETD system QS-B220 was used. The IMS performance is demonstrated on three target compounds, TNT, RDX and PETN. The results’ evaluation of this semi-quantitative screening is carried out by using statistical methods for reliability assessment, such as probability of detection (POD) and receiver operating characteristic (ROC). Their detection limits with a POD = 0.90 are determined after swab sampling on various surfaces. These screening results provide an objective decision-making aid to responsible control personnel in addition to x-ray measurements, whether there are or are no dangerous substances or objects in the cargo. *) ECAC = European Civil Aviation Conferencezeige mehrzeige weniger
