Surface acoustic wave (SAW) sensors have been coated with different organic polymers. Their sensitivities and selectivities towards gaseous solvents such as water, methanol and automotive fuel in dry air are determined. Four sensors are combined to form an array and a pattern-recognition technique (
The paper presents experimental results of the interaction of thin layers (83 and 310 nm) of lead phthalocyanine (PbPc) with trace amounts of toxic gas NO2 in a system with an acoustic surface wave on a LiNbO3 Y-Z substrate. PbPc films were prepared according to the usual vacuum evaporation method.
Nitrobenzene and water adsorption isotherms were obtained on an aminopropyltriethoxysilane coated surface acoustic wave sensor (SAWS) at < 5, 17, 33 and 47% relative humidity (RH) at 6, 13, 2.5 and 47Β°C. The nitrobenzene isotherms were BDDT type 1 (Langmuir) and water isotherms BDDT type 3. The nitr
