If you want to geek out on eNoses, there is a lot of information out there. The article referenced above doesnâ(TM)t get into much detail, but there are basically three different techniques that are commonly used: mass spectrometry, used by companies like Torion , gas chromotography, used by companies like Seacoast Science, Inc, and some of the newer systems use optical sensor systems, used by QualSec. Of these I like the optical sensors the best, because some of them can detect in the parts per Billion, or even parts per Trillion! Take that smellhound!
The best academic source on eNoses and future trends, which is pretty approachable, is available from the American Chemical Society. It includes a summary of the different approaches and applications, like for disease diagnosis, environmental monitoring and use with the food and beverage industry. Coming soon to a supermarket/hospital/factory/Superfund site near you!

Bah! My links didn't work. Here they are: Torion: http://www.torion.com/ Seacoast Science: http://www.seacoastscience.com/ QualSec: http://www.qualsensors.com/ American Chemical Society article: http://pubs.acs.org/cgi-bin/sample.cgi/chreay/2008/108/i02/html/cr068121q.html Maybe these won't work either. But I tried!
