In the context of the Second “EU Conference on Detection of Explosives” (https://eucde.net) in 2013 in Rome (Italy), SEDET CEO, Mr. Gonzalo Fernandez de la Mora, delivered a lecture highlighting recent performance improvements achieved by ACES, the explosive vapour screener developed by SEDET.
The Conference was scheduled following the success achieved by the First European Conference on Detection of Explosives, which took place in 2010 (Avignon, France). The theme of this new event was “Closing the gap”, and the aim was to evaluate progress in explosives detection technologies, and future needs to counteract the increased and diversified security threat. Appropriate detection techniques are needed in order to increase the security of citizens in public places and large events, and to protect critical infrastructure, aviation and other public transport systems.
The Air Cargo Explosives Screener (ACES) is a vapour detector developed by SEDET, able to screen explosives while cargo is in "bulk" form, in particular, complete trucks at the airport entrance. ACES increases security through a PoD higher than current technologies, while simultaneously it reduces screening costs and delays to values well below present operations.
ACES technology (Explosives Vapor Detection-EVD) is based on the integration of Differential Thermal Desorbtion (DTD), Secondary Electro Spray Ionization (SESI), Differential Mobility Analysis (DMA), and API Tandem Mass Spectrometry (API MS / MS), in the development of a new theory on vapour detection.
In his lecture, Mr. Fernandez de la Mora showed latest results from operational tests conducted on ACES, and presented with great detail aspects previously unknown on vapour detection, such as effects of confinement, soaking, temperature and type of cargo. His presentation was completed with a new theory which might help interpret test data.
