Defiant's Canary-Two™ — Hand Held Gas Chromatography

Canary-Two™ is a platform technology that can be tailored to meet many applications. Contact us to see how Canary-Two™ can be tailored for your application.

	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.

	Defiant’s Canary-Two™ chemical sensor system completes an analysis in two minutes. With the on board battery, Canary-Two™ can operate continuously for 4 hours. Canary-Two™ uses ambient air; no specialty gases are needed for operation. In hand held applications, Canary-Two™ will report chemical identification and concentration to a 4 line graphical display. Chromatograms are displayed on screen. For remote applications (e.g. facility monitor, UAV/UGV payload) Canary-Two™ can report chromatographic data via serial port. Package dimensions are 7 ½”L x 5 1/16”W x2 1/8” D.

	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.
