The response of some organic microsensor coatings to a variety of vapors.
Six organic compounds were spray-coated onto surface acoustic wave devices which were then exposed to vapors of acetone, diethyl ether, dichloromethane, chlorobenzene, benzene, and acetonitrile. Changes in the resonant frequency of the device or in the resistance of the coating were collected by computer-controlled data acquisition. Different patterns of response to the six vapors were observed for each of the coatings.
