Zusammenfassung:In this paper, we present a comparative study of GB and DMMP vapor detection using Love wave devices. Acoustic sensors are optimized versus the mass loading effect according to theoretical results, and a specific sensitive coating based on polysiloxane polymer is used to ensure selectivity. Experimental results allow us to compare the interactions between the coating and both gases. An estimation of the diffusion coefficient of each gas (GB and DMMP) was performed and we linked the dynamic of the responses with the sorption kinetics.
