ABSTRACT:
A combined analyzing apparatus includes (i) a front end unit including a photoacoustic spectroscope that takes a gas sample inside and analyzes the gas sample by a photoacoustic spectroscopy, (ii) a light analyzing apparatus that takes the analyzed gas sample inside and analyzes the gas sample based on a change of light which is transmitted through the gas sample, and (iii) a mass analyzing apparatus that further takes the analyzed gas sample inside and analyzes a mass of an ingredient of the gas sample. The combined analyzing apparatus also includes (iv) a battery that supplies the front end unit, and the light analyzing apparatus and the mass analyzing apparatus with electric power source, and (v) a portable case that houses the front end unit, the light analyzing apparatus, the mass analyzing apparatus and the battery.
