Test samples of energetic material, especially explosives, are heated under reduced pressure below 20mbar and light emission, particularly chemiluminescent emission, measured to indicate presence of explosive. A photomultiplier or photodiode may be used for measurement. Heating is to e.g. 300 - 500deg.C. Apparatus for the detection has a heated chamber with one of its walls transparent to light, pumps for keeping the chamber under a reduced pressure, a detector for emitted light measurement and a sample port. |
