Gas detection apparatus based on SAW/GC was gained by combining Surface Acoustic Wave (SAW) gas sensor with gas chromatography (GC). Because of its features as high sensitivity, more detectable gas types and resolution of crossed-interference, the SAW/GC gas detection apparatus is perfect for the gas composition analysis in the complicated atmosphere background especially. In this paper, the main...
This paper reports some work on SAW gas sensors based on the condensation-adsorption effect relating to the sensing position of the SAW detector in GC/SAW gas sensor system, and analyzes the response of GC / SAW gas sensor system influenced by the position of the SAW detector where the GC column outlet is aligned at. The SAW device aligned at different position is used in GC/SAW for the detection...
