Abstract
Systems and methods are provided for tracking all chemicals, including odors, a package is exposed to throughout the shipping process. A device is attached to the package or placed within the package to extract the chemicals that are in the surrounding environment to the device. The device can extract and concentrate volatile, semi-volatile and non-volatile chemicals that the device and the corresponding package are exposed to throughout the shipping process. The extracted chemicals may then be desorbed from the device and analyzed by an analytical instrumentation method.
