Carbon isotope analysis device and carbon isotope analysis method |
| abstract |
Provided are a carbon isotope analysis device high in partial pressure of carbon dioxide isotope in gas sent into as optical resonator, and high in sensitivity performance and analytical accuracy, and an analysis method by use of the carbon isotope analysis device. A carbon isotope analysis device including a carbon dioxide isotope generator provided with a combustion unit that generates gas containing carbon dioxide isotope from carbon isotope, and a carbon dioxide isotope purifying unit; a spectrometer including an optical resonator having a pair of mirrors, and a photodetector that determines intensity of light transmitted from the optical resonator; a carbon dioxide trap including a cooler for freezing the carbon dioxide isotope, the carbon dioxide trap being disposed between the carbon dioxide isotope generator and the spectrometer; and a light generator. |
