ABSTRACT:
An adsorbent coating is affixed to the internal wall of a sealable container. The container may be rigid or flexible. The adsorbent coating, when in the sealed container retains odor components for an extended period permitting the odor components to be transported without requiring the transport of the source of the components. Thermal, or other desorption techniques release the odor components for analysis by, for example, liquid chromatography or gas chromatography. One embodiment of the invention is disclosed in which the container is a flexible bag, coated on its interior with an adsorbent material. In another embodiment of the invention, a large surface-area body, containing sorbent material on its surfaces, is contained within the container.
