• Description:
  Coated surface acoustic wave (SAW) chemical sensors were developed for the selective measurement of toxic olefins and dienes. Specific attention was given to styrene (100425), ethyl-acrylate (140885), 1,3-butadiene (106990), acrylonitrile (107131), beta-chloroprene (126998), vinyl-chloride (75014), and vinylidene-chloride (75354). The device as constructed consisted of a piezoelectric substrate with two sets of interdigitated metal-electrode transducers deposited on the surface. The coating reagents used were all members of a class of square planar platinum olefin pi coordination complexes of the general formula trans-PtCl2(olefin)(amine). They were designed to react via substitution of the initially bound olefin with certain olefins and dienes, forming stable products. By monitoring the rate of frequency change of the SAW sensor, the steady state rate of mass change accompanying the olefin substitution reaction could be measured, allowing real time monitoring of air levels of the analyte. Each of the target compounds was measurable using this general approach, with the exception of vinylidene-chloride. A prototype battery powered field instrument was designed and constructed which provided real time measurement of olefin and diene vapor concentrations, coating regeneration functions, and data logging capabilities.
