✦ Synopsis


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.

Surface acoustic wave (SAW) sensors have been coated with different organic polymers. Their sensitivities and selectivities towards gaseous solvents such as water, methanol and automotive fuel in dry air are determined. Four sensors are combined to form an array and a pattern-recognition technique (
