E-Nose

An Electronic Nose (Cyranose 320) is used to analyze patterns of VOC's in samples of exhaled air.

The analytical system of the Cyranose 320 is based on a 32-carbon sensor array; a Nose-chip; reacting with the organic volatiles in the presented samples. The sensors react by absorbing and expanding, and the result is a difference in electronic resistance through the Nose-chip resulting in a smell print for each sample (Figure 1).
