Polymer-coated sensor arrays for organic vapor detection

Arrays of polymer-coated surface acoustic wave (SAW) vapor sensors have shown great promise for detecting a variety of organic vapors at relevant levels. Both modeling studies and experimental studies have shown that many toxic organic vapors can be detected at or below permissible exposure limits. However, single sensors are not adequately selective for many applications. Sensor arrays with chemometric data processing offer a means to greatly increase the selectivity of the analytical measurement. We have recently completed the collection of a large data set where twenty diverse polymers coated on SAW devices were tested against 18 organic vapors and water. With these data in hand, it is possible to examine a variety of issues associated with the development of SAW sensor arrays and selection of polymers for the arrays.
