摘要： A process whereby the olfactory response of a gas chromatograph, equipped with a focused surface acoustic wave interferometer integrating detector is converted to a visual image for the purpose of performing pattern recognition. As volatile analytes exit a gas chromatography column a Surface Acoustic Wave Interferometer is used to monitor the condensation and re-evaporation of these analytes by periodically measuring the resonant frequency of the interferometer. A time varying output parameter is then converted to a polar display. This form of electronic nose provides a recognizable visual image of specific vapor mixtures (fragrances) containing possibly hundreds of different chemical species. Because the method provides a means of adapting and learning to recognize new vapors using these images, it is a useful method for testing chemical compositions as well as the vapors associated with bacteria and human disease.
