Abstract
Over the last decade, there has been great interest in chemical applic ations of acoustic wave devices, especially those using surface acoust ic waves (SAWs). This work deals with the sensing of an organophosphor us gas using a SAW delay line spin-coated with a specific organic comp ound. The sensing cell as well as the measurement bench are completely described. Reproducible responses to pollutant concentrations from 10 to 100 ppm at various temperatures (25, 30 and 50 degrees C) are pres ented. The described sensor has a sensitivity of 27 Hz ppm(-1) at 30 d egrees C.
