A method and an apparatus for characterizing the barrier properties of an array of coatings. The method including providing a plurality of acoustic wave devices, wherein each of the plurality of acoustic wave devices comprises at least one surface, and providing a plurality of coating materials suitable for forming a plurality of coatings on the at least one surface of each of the plurality of acoustic wave devices. The method also including coating each of the plurality of acoustic wave devices with at least one of the plurality of coating materials to form a plurality of coated acoustic wave devices and measuring a predetermined output parameter of each of the plurality of coated acoustic wave devices. The method further including exposing the plurality of coated acoustic wave devices to an analyte vapor of a predetermined concentration, measuring the predetermined output parameter of each of the plurality of coated acoustic wave devices, and correlating a change in the predetermined output parameter of each of the plurality of coated acoustic wave devices to the barrier properties of each of the plurality of coatings.
