The feasibility of a vibrating piezoelectric crystal as a CW agent detector was assessed by applying CW agent-sensitive coatings to the crystal and testing the detector with 0.3 mg/cum of GB (Sarin). Eight different coating materials were selected, based on previous data with G-agent simulants. No responses were observed to 0.3 mg/cum. GB, but three costings (XAD-4/Cu(2=)-diamine, polyethylenemaleate, and succinyl choline chloride) gave responses of -59 Hz, -22 Hz, and =11 Hz, respectively, to 10 mg/cm.of DIMP (diisopropyl methylphosphonate). Circuit optimization and the use of an operating frequency higher than 9 MHz is recommended to enhance sensitivity. Far-term recommendations are to apply the same coatings to a high-frequency (e.g., 300 MHz) surface acoustic-wave device and test again with CW agents.
