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. A new pattern recognition method was developed maximizing the selectivity and accuracy of detection of vapor contaminants as were several predictive models of sensor responses. These models were based on vapor boiling points, coating/vapor solubility parameters, and coating/vapor solvation parameters in conjunction with linear solvation energy relationships. 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.
