Claim:
1. A method of training a canine to detect, by smell, an odor emanating from a material to be detected, comprising: selecting an odor component, capable of volatilizing at room temperature, of the material to be detected, wherein the odor component is present in a headspace of the material to be detected; dissolving the odor component, capable of volatizing at room temperature, of the material to be detected in an organic solvent, wherein the material to be detected is selected from the group consisting of propellants, lead azide, lead styphenate, mercury fulminate, and sheet explosives; absorbing the dissolved volatilizable component and organic sorbent onto an absorbent material; evaporating the organic solvent from the absorbent material prior to packaging the absorbent material in an inner container; packaging the absorbent material in the inner container that is permeable to said volatilizable component; packaging the inner container in an outer container that is impermeable to said volatilizable component, the outer container being size to maintain a space between the inner and outer containers, the space having a desired volume for permeation of a known concentration of the volatilizable component into the space; forming the known concentration of the volatilizable component in the space by maintaining the inner container in the outer container to allow the volatilizable component to permeate through the inner container into the space until the desired volume is filled with a concentration of the volatilizable component and an outer surface of the inner container is saturated with a concentration of the volatilizable component such that the known concentration of the volatilizable component is provided immediately upon removal of the outer container; removing the outer container, exposing the known concentration immediately upon removing the outer container, the known concentration being sufficient for detection by the canine; disposing the inner container in a location accessible for the canine to detect the volatilizable component permeating through the inner container; and releasing the canine in the location to detect the odor of the volatilizable component permeating through the inner container.
