Zusammenfassung:PROBLEM TO BE SOLVED: To obtain an analyzer for a carbon isotope, which can be handled at a low cost and simply by using an adsorbent. SOLUTION: An adsorption tube 11 into which an adsorbent is put or a CO2 sampling kit is used, and the adsorption tube 11 or the CO2 sampling kit is maintained in a prescribed pressure decreased state. Then, a heating device 12 is urged, a gas is desorbed so as to be introduced into a sample cell 20, the spectral intensity of CO2 and that of CO2 are measured by an analysis part 10, and an isotope ratio is found on the basis of their intensity ratio.
