摘要：

Coated surface acoustic wave (SAW) sensors can be used for the determination of organic solvents in ambient and exhaust air. Experiments using analytes dissolved in dry and moist air show that response times of the order of one second can be achieved. The influence of humidity on sensor performance is presented. An example of additive behaviour of coatings with analyte mixtures is given.
