Morpho Detection Inc.'s XRD 3500 X-ray Diffraction-based explosives detection system (EDS) can accurately distinguish explosives from non-threat materials in luggage without the need to open the bag or remove its contents. The unit's low false alarm rate results in a simplified inspection process. The technology identifies materials based on their molecular composition, not densities or other less distinctive characteristics. As a result, the unit can identify potentially threatening substances in many forms, including powders, solids and liquids. The device recently passed testing to meet European Civil Aviation Conference (ECAC) Standard 3 technical specifications, the requirement for complying with the European Union's Standard 3 for hold baggage screening.
