Electrochemical detection of explosives in air
First Claim
1. A portable device for detecting at least one explosive substance present in air, the device comprising:
- (a) a mechanism for drawing an air sample into the device;
(b) a solid trapping material having a surface for trapping a portion of particles of an explosive material in said air sample;
(c) a collector for containing a solvent, said collector associated with said surface, said solvent for producing dissolved explosive material by;
(i) removing and dissolving said portion of particles from said surface, and (ii) directly dissolving a remainder of said particles of said explosive material, (d) an electrode unit, associated with said collector, for producing a signal corresponding to a presence of said dissolved explosive material, and (e) circuitry for determining said presence of said dissolved explosive material based on said signal produced by said electrode unit.
