Florida International University (FIU) is pursuing a business partner interested in developing and commercializing a method of training a canine to detect target odor chemicals using controlled odor mimic permeation system (COMPS).
The use of canines as a method of detection of explosives is well established worldwide and those applying this technology range from police forces and law enforcement to humanitarian agencies in the developing world. Despite the recent surge in publication of novel instrumental sensors for explosives detection, canines are still regarded by many to be the most effective real-time field method of explosives detection. However, unlike instrumental methods, it is currently difficult to determine detection levels, perform calibration of the canines’ ability or produce scientifically valid quality control checks. In addition, the problem of odor contamination between detector dog training aids requires complex storage needs.
FIU inventors have developed a canine training method using controlled odor mimic permeation system (COMPS). The COMPS consists of a permeable polymer container chosen to suit target odor and release rate required, stored inside a non-permeable package. The design allows for the pre-equilibration of the target odors such that the outer surface of the inner package can saturate with odor during storage, and resolves the odor contamination issue with the non-permeable outer package. Removal of the inner item then provides an instant and reproducible source of known target vapor flux. This technology has been successfully demonstrated by placing the target odor chemicals within permeable membranes such as low density polyethylene which are then sealed within a non-permeable membranes such as metallized polyester.
Can be used to train canines for detecting odor components that are capable of volatizing at room temperature; non limiting examples include odor components emanating from explosives, drugs, human remains, and live human scent.
- Simple to use, reproducible, and field deployable
- Prevents cross contamination when storing multiple odor targets (5-10 targets are commonly employed)
- The rate of permeation can be controlled to provide a known amount of odor over a set time
