Abstract
A new zeolite-containing coating is proposed for surface-acoustic-wave (SAW ) sensors. It was found that the frequency of a SAW sensor increases in the reaction of ammonia with the zeolite-containing coating in a humid atmosph ere, which provides the selective determination of ammonia at a level of te nths of a percent in ambient air with humidity higher than 10%.
