A chemical sensing system based on arrays of surface acoustic wave (SAW) resonators has been developed for identification of S- and N-containing Compounds. The four resonators in the array are coated with four kinds of different chemoselective polymers: triethanolamine (TEA), nano-fibular polyaniline (PANI), glutamic acid hydrochloride (GAH) and multi walled carbon nanotubes (MWCN) modified with tungsten trioxide, which are used for the detection of harmful gases H2S, SO2, NH3 and NO2 respectively. The harmful gases were detected under room conditions, the response time, the response value, the recovery speed and the detection tendency are obtained. The characteristics of various gases are extracted from the experiment datum. The datum is processed and Pattern recognition algorithms are developed to identify four different of gases. The stability experiments are also made to prove the accuracy of the results of the detection. It is concluded that the harmful gases, including H2S, SO2, NH3 and NO2, could be detected rapidly and accurately by the SAW array sensor.
