Microsensor Arrays for the Identification of Organic Solvents Vapors.

PB94151560

Publication Date	1993
Personal Author	Zellers, E. T.
Page Count	190
Abstract	The use of microfabricated surface acoustic wave (SAW) chemical sensor arrays for the measurement of organic solvent vapors in the workplace was described. Performance parameters involved in the use of instrumentation employing SAW chemical sensor arrays were examined in several laboratory investigations. The instrument used in these studies included an array of four sensors coated with each of 16 different isotropic polymer coatings. The author concludes that the individual identification and quantification of a large number of vapors in binary and ternary mixtures is possible using a simple four sensor array.
