Electronic Noses and Olfaction 2000 reflects the state of progress toward the development and application of electronic instruments called electronic noses (e-noses). These instruments are generally based on arrays of sensors for volatile chemicals with broadly tuned selectivity, coupled to appropriate pattern recognition systems. They are capable of detecting and discriminating a number of different simple and complex odors, such as the headspace of coffee and olive oil, as well as being able to perform simple multicomponent gas analysis. Written by international scientists, engineers, technologists, clinicians, investigators, and instrument manufacturers working in the applied research of e-noses as well as in the applications of olfaction and taste, this volume is essential reading for anyone who wants a review of the latest developments in odor sensors, instrumentation and signal processing, and their medical, agricultural, and food-related applications.Figure 3 Sensor polarisation circuits Figure 4 Measurement unit The analog to digital conversion is made with 16 differential input 24 bit Sigma ... A stepper motor control interface working from 0 to 0.1 kHz regulates the insertion of the needle into the vial and the positioning of the vials. The electrovalves were controlled by open drain sink with maximum load current of 100mA and working voltage 12VDC.
