Bottled Liquid Scanner for Security Checkpoints
Sealed bottles of any opacity are automatically inspected for hazardous liquids in seconds using a novel Nuclear Magnetic Resonance method. Liquid explosives and explosive precursors such as hydrogen peroxide are detected using a multi-element Nuclear Magnetic Resonance protocol, solving the shortcomings of optical techniques. The Bottled Liquid Scanner is capable of inspecting multiple bottles in a single scan with unprecedented low false alarm rates, ensuring minimal or no disruption at security checkpoints.
