Using gas chromatography column, the selectivity ofthe SAW gas sensor were introduced. Experimental results, which show the phase change of output signal under theabsorption of volatile gas on sensor surface, were presented. This SAW gas sensor system may be well suited for a highperformance electronic nose system. 한국센서학회 가스 크로마토그래피를 부착한 표면탄성파 가스 센서 Surface acoustic wave gas sensors by assembling gas chromatography column Article 2 센서학회지, v.16, no.1, pp.39 - 43 센서학회지 16 1 39 43 kci ART001040378 SAW quartz gas chromatography column gas sensor phase shift electronic-nose
