Explosive Residue Detector
| Researcher Contact: Judy Fu |
Electrochemical sensors are being developed for both vapour phase detection
of nitro group explosives, hydrazine and organophosphonates in the field.
These sensors are based upon a three-electrode cell and an amperometric
technique for continuous detection. Appropriate selection of solid polymer
electrolyte (SPE) membranes improves the sensor's selectivity, and enhances
the capability for detecting vapour phase explosive residues. The electrochemical
sensors have shown a sensing capability for the nitro group present in many
explosives. |

| Wireless Results |
A new self-contained portable chemical sensor has been developed to speed
up the characterization of chemicals in the field. Here we apply an electrochemical
sensor system for explosive residue detection. Results from this collaborative
project are shown below.
