Explosive Trace Detection

Explosive Trace Detection (ETD) is a technology used to identify tiny residues of explosive materials on surfaces or objects. It works by collecting a small sample—like swabs or particles—and analyzing it with specialized instruments, such as mass spectrometers or ion mobility spectrometers. These devices can detect chemicals related to explosive substances even in extremely small amounts. ETD is commonly used in security settings like airports to prevent threats without causing delays, providing a quick, non-destructive way to ensure safety by identifying potential explosives before they can be used maliciously.
