Gas phase chemical detection with an integrated chemical analysis system

Casalnuovo, Stephen A.; Frye-Mason, Gregory C.; Kottenstette, Richard J.; Heller, Edwin J.; Matzke, Carolyn M.; Lewis, Patrick R.; Manginell, Ronald; Baca, Albert G.; Hietala, Vincent M.

Microfabrication technology has been applied to the development of a miniature, multi-channel gas phase chemical laboratory that provides fast response, small size, and enhanced versatility and chemical discrimination. Each analysis channel includes a sample preconcentrator followed by a gas chromatographic separator and a chemically selective surface acoustic wave detector array to achieve high sensitivity and selectivity. The performance of the components, individually and collectively, is described.
