Technology
1. A gas sample is captured by Selective Collection on a collector, or Preconcentrator. 2. The targeted chemicals are thermally desorbed in a sharp, concentrated pulse. |
 1st Stage Selective Preconcentration.
Only targeted chemicals collect on the preconcentrator. |
3. In the Canary-Zero™ systems, the sample pulse moves to a Detector where it is captured in by Selective Collection. 4. The detector "weighs" the sample to determine the analyte concentration in ambient air. |

5. In Defiant's Canary-Three™ system, the sample pulse enters a Micro Gas Chromatography Column before moving to the detector. The micro GC column separates chemicals from each other for identification. |
 2nd Stage Micro Gas Chromatography.
The GC column separates the red compound from the blue.  Canary-Three™ Schematic
|
6. An option for the Canary-Three™ system uses dual detectors; one in combination with a micro GC column and one without. This enables Intelligent Sampling. The user may operate the system without the GC for a quick survey of the surroundings, or may switch in the GC for a more complete analysis. |
