Abstract: This document describes a gas sampling device. The gas sampling device is capable of housing sensors printed on thin film (e.g., paper) and is operable to expose the sensors printed on the thin film to air for a brief period of time to sample the air for smells. The exposure causes a chemical reaction between the sensors and the sampled air and differs depending on the smells of the sampled air. After exposure, an image of the reacted sensor is captured. The image is analyzed according to image processing techniques to recognize the smells of the sampled air. The gas sampling device is also capable of concurrently sampling air from a surrounding environment along with sampling air from a specimen of interest. By analyzing both samples, the smells of the specimen of interest can be distinguished from those of the surrounding environment. Once the smells are ascertained, a profile of chemical groups in gases of the sampled air is output.
