The Langmuir-Blodgett layer deposited on one channel of the bi-channel sensor delay line is proposed as chemosensitive element of a ultrasonic chemical sensor. Chemical composition of this layer is an equimolar mixture of 5-[[1,3-dioxo-3- [4- (1-oxooctadecyl) phenyl] propyl] amino] - 1,3 - benzenedicarboxylic acid (DA) and cetylamine (CA). The thickness of this layer is equal to dimension of one molecule. The chemical sensitivity of this layer to some mixtures of air with vapor of volatile organic compounds has been investigated.
