Isotopomer absorption spectrochemical analysis method and apparatus therefor |
摘要 |
An isopotomer absorption spectrochemical analysis method and apparatus therefor for precisely measuring the isotope ratio with a simple structure even if the substances to be measured have concentrations greatly different from each other. An isopotomer absorption spectrochemical analysis apparatus has a wavelength stabilization-cum-measurement gas cell (6) serving as both a wavelength stabilization gas cell used for wavelength stabilization control of measurement of a high concentration substance to be measured and a measurement gas cell by selecting an absorption coefficient of the high-concentration substance which is lower than that of a low-concentration substance to be measured so that the absorption signal levels of the substances having greatly different concentrations in the same cell may be substantially equal to each other. |
