  5. A New Electronic Nose Using Acoustic Technology

A new Electronic Nose using a single, uncoated, high Q surface acoustic wave resonator is described. The commercial expression of this technology, the zNose®, is now providing an on-line quantitative measure of quality for food, beverages, cosmetics, and other manufacturers of aromatic products. The zNose® can provide a recognizable visual image of specific vapor mixtures (fragrances) containing possibly hundreds of different chemical species in less than 1 minute or near real time. At the same time, this advanced electronic nose is able to speciate and quantify the individual chemicals (hydrocarbons mainly) present in any vapor, odor, or smell. Because the new acoustic technology is quantitative it is the only electronic nose technology to be validated by the US EPA.
