Claim:
1. A method for measuring an atmospheric concentration of a compound, comprising steps of: providing an adsorptive tag within a target atmosphere for a period of time to allow adsorption of a compound of interest for measurement, wherein the adsorptive tag comprises a substrate, a heating element disposed on or within the substrate and an adsorptive element disposed on the substrate over the heating element; removing the adsorptive tag from the target atmosphere after said period of time, and placing the adsorptive tag within a closed measuring space with electrical contacts of said heating element brought into connection with an electrical power source; heating the adsorptive element to cause de-adsorption of the compound of interest into the closed measuring space; measuring a concentration of the de-adsorbed compound of interest within the closed measuring space; and determining a concentration of the compound of interest in the target atmosphere based on the concentration of the compound of interest within the closed measuring space.
