| titleOfInvention | A METHOD AND APPARATUS FOR ANALYZING AN ISOTOPIC GAS SPECTROMETRICALLY |
| abstract | In accordance with the present invention, a test gas sample containing carbon dioxide 13 CO2 as a component gas is introduced into a cell, then the absorbance of light transmitted through it is determined at a wavelength suitable for the component gas 13C02, and the concentration of the component gas is determined based on a calibration curve prepared through measurement on test gas samples containing the component gas in a known concentration. Also, the concentration of water vapor contained in the test gas sample is measured and the concentration of the component gas in the test gas sample is corrected according to the measured water vapor concentration based on a corrective curve prepared through of the measurement of test gas samples containing water vapor in a known concentration (fig. 4). With spectrometry the concentration ratio of the component gas can be accurately determined and corrected by measuring the moisture content in the test gas sample. |
