It is needed to detect a wide variety of dangerous gases in environment and for security use. Gas chromatography has been used for this purpose, but the compactness and gas recognition ability are not enough. Thus, we propose a new approach to separate the gases using separation column and monitor them by a ball SAW sensor. As a preliminary test, both delay time and amplitude responses were observed with water-ethanol solution, and found different recovery time of response. With 4 alcohol mixed solution, each amplitude response was observed correspondently. Amplitude response reflecting the leaky loss of SAW was observed with hydrogen-nitrogen mixed gas. Approximate equation of leak loss nearly agreed with experimental results, suggesting a possibility of quantitative analysis using the leaky loss.
