Ultra high-speed gas chromatography (GC) fitted with an odor sensor is a powerful tool for analyzing the chemical vapors produced by explosives or other chemical or biological weapons. 

The human nose is often considered the best gas sensor, as the odor contained in the gas permits detection at levels as low as 190ppm or 0.01 per cent in air. Gas detectors are, however, sometimes used to give additional warnings of any leaks. The following points should be borne in mind when considering such an application ... 

The sensor response depends not only on the polarity of the analyte, but also on the flow environment. In the mammalian olfactory system, the nasal cavity structure plays an extremely important role in odor discrimination13. 

Chemical sensors are widely used to monitor hazardous and combustible gases [65]. Applications include safety control in industrial applications, surveillance of boilers and other devices which are operated with natural gas as well as more sophisticated areas like cooking control and odor determination [66]. 

A sensor array named the electronic nose is a rapid and relatively simple technique that can be used for monitoring wastewater odors (Stuetz et al., 2000). The electronic nose uses sensors of varying affinities to characterize an odor without reference to its chemical composition. 

The results demonstrate (i) that in turbulent odor plumes, purely chemical spatial gradients can be calculated when measuring with sensors scaled to lobster olfactory organs, (ii) that rapid odor access to the lobster s olfactory organs (under low ambient flow conditions) is accom-... 

These systems are formed by a number of cooperating individual non-selective sensors, whose outputs are processed to form chemical images or, in the presence of odors, olfactory images.
