Canary-Two™. This chemical sensor system is capable of reporting a complete high
confidence analysis of chemical warfare agents in a matter of 2 minutes. Unlike other commercial systems, Canary-Two™ uses ambient air as the carrier gas
so there is no need to carry or refill gas bottles. The system is handheld or can be emplaced in a sensor network for continuous protection. Every 2
minutes, this system will specifically identify sarin, soman, sulfur mustard, etc and their relative concentrations.

Defiant's modular manifold accepts the key system components (micro pre-concentrator, micro GC column and micro SAW
array detector). The manifold provides fluidic and electrical connections for each component. |

What can chemical selectivity
do for you? ? The system was introduced to a mixture of three chemicals.
Two chemicals were target chemicals DMMP and Methyl Salicylate (MES).
The third was an industrial solvent, methylene chloride, at a concentration
a few orders
of magnitude higher than the DMMP and MES. Canary-Two™ shows little or
no response for very high concentrations of an interfering chemical like methylene
chloride. However, the very small amounts of chemical surrogates for sarin gas
(DMMP) and mustard gas (MES) produce a very large response. Both are detected
in the same analysis but reach the detector at different times thanks to an integrated
micro gas chromatography.
