Electronic Noses and Olfaction 2000

摘要: The concept of the electronic nose has attracted attention in many branches industry for its potential routine odour analysis. Being first reported 1982 by Persaud and Dodds, research field rapidly increased, a number companies have now been established to commercialize concept. Basically, an mammalian olfaction as model consists sensor array with partially overlapping selectivities pattern recognition system. It can be trained detect discriminate large both simple complex odours. In 1994, manufacturer AlphaMOS France initiated symposium promote bring together representatives from industries field. since held annually, alternately Europe USA. 2000, 7th on subject, called International Symposium Electronic Noses (ISOEN), was at Brighton, UK, this book, Olfaction series papers presented event. 44 contributions contains broad mixture state-of-the-art papers, covering aspects such new concepts, instrumentation, data processing methods applications. part, entitled Odours, Taste Physio-Chemical interactions, excellent overview oral malodour is presented, including 60 references. This section also includes description tongue (yes, you measure aqueous solution it), based similar strategies nose. next section, Sensors/Instrumentation, various principles are described, which conducting polymer FET, amperometric devices impedance spectroscopy mentioned. Sensor performance affected ageing degradation surface, causing drift effects. third part devoted Data Processing, some compensate presented. Methods selection well fuzzy logic artificial neural nets. two sections, Medical/Microbial Applications: Food, Agricultural Environmental, different applications microbial growth, quality measurements olive oils, wheat raw milk odour, search truffles portable nose, monitoring hot flue gases, emissions agriculture automotive trim materials. These five sections book cover current development areas noses. Especially valuable dealing algorithms signal reduction, area increasing importance. Also interesting application detection. A deals estimation oils - trend? Contributions noses techniques ion mobility spectroscopy, mass or gas chromatography were not given, however, sample handling procedures only sparsely reported, that important technology. There no real industrial reported. aimed researcher instrument makers people general interest it gives good update what happens area. Fredrik Winquist
