Abstract: The present invention provides a novel analysis and detection device, which includes a separation unit for separating a plurality of single-component gases from the mixed components of a gaseous sample; a detection unit for producing a sound signal in response to a corresponding one of the single-component gases; and a signal receiving unit for transferring the sound signal into an electronic signal. The device of the present invention uses gas chromatography principle to separate mixed components of a gaseous sample, a plurality of single-component gases are formed to be detected, a sound signal is formed in response to a corresponding one of the single-component gases, and the components and their amounts are determined according to occurrence time and frequency of the sound signal. The present invention is applicable to a rapid detection and a quantitation analysis of a gas.
