Abstract

See full text

A carbon isotope analyzer 1 includes a carbon dioxide isotope generator 40 that includes a combustion unit that generates gas containing carbon dioxide isotope from carbon isotope, and a carbon dioxide isotope purifying unit; a spectrometer 10 including an optical resonator 11 having a pair of mirrors 12, and a photodetector 15 that determines the intensity of light transmitted from the optical resonator 11; and a light generator 20 including a light source 23, a first optical fiber 21 to transmit a light beam from the light source 23, a second optical fiber 22 for wavelength conversion, the second optical fiber 22 splitting from the first optical fiber 21 at a point and combining with the first optical fiber 21 at another point downstream of the splitting point, and a non-linear optical crystal 25 that generates light having the absorption wavelength of the carbon dioxide isotope on the basis of the difference in frequency between light beams transmitted through the optical crystal 25. The carbon isotope analyzer 1 is a simple and convenient apparatus that can analyze isotope 14C.
