The Explosives Trace Detection Laboratory consists of a selection of Explosive trace detection (ETD) equipment currently used in EU airports. This equipment has become a key technology in civil aviation security screening processes in Europe, playing a front-line role in the detection of explosives at passenger checkpoints, and for the screening of staff, supplies, hold baggage and cargo. Moreover, in this laboratory, there is also a selection of handheld detection equipment, which is used for both explosives and narcotics trace detection in other fields than aviation by security officers, first responder, law enforcement and custom officers. The Explosives Trace Detection Laboratory is part of the Border Security Research Infrastructure, that supports EU policies by enhancing testing capabilities, promoting best practices and facilitating the testing and verification of security-threat detection equipment.
