In a measuring method for measuring an atmospheric concentration of a compound, such as a volatile organic compound (VOC), an adsorptive element is provided within a target atmosphere for a period of time to allow adsorption of a compound of interest, and then removed from the target atmosphere, and placed within a closed measuring space. The adsorptive element is heated within the measuring space to cause de-adsorption of the compound into the closed measuring space, and a concentration of the de-adsorbed compound is measured. A concentration of the compound in the target atmosphere is determined based on the concentration of the compound within the closed measuring space. The adsorptive element may be formed of an adsorptive material such as carbon fibers, cellulose or other adsorptive materials, and a binder. The adsorptive element may be optimized for adsorption of a specific compound.
