摘要
A feasibility study of the combination of the flow-injection analysis (FIA) technique with the piezoelectric acoustic wave sensor (thickness-shear mode, TSM) is described. Flow-injection systems provide a method to relate the hydrodynamic response of the sensor to the concentration-time profile of the analyte produced by the dispersion behaviour of sample zones. Network analysis of the TSM sensor generates Multi-dimensional information on the bulk properties of the liquid sample and surface properties at the liquid/solid interface. The relationship between acoustic energy transmission and the interfacial structure, viscosity, density and dielectric constant of the analyte is discussed. The FIA-TSM system provides a rapid, reproducible detection method with enhanced sensitivity and scope.
