ISOTOPIC GAS ANALYZER AND METHOD OF JUDING ABSORPTION CAPACITY OF CARBON DIOXIDE ABSORBENT |
摘要 |
<p>A method of judging the absorption capacity of a carbon dioxide absorbent for use in an isotopic gas analyzing method for measuring the concentration of carbon dioxide 13CO2 in a gas specimen containing carbon dioxide 13CO2 and carbon dioxide 12CO2 as component gases, comprising: performing a first light intensity measuring process by introducing air having passed through a vessel containing carbon dioxide absorbent into the cells; performing a second light intensity measuring process by introducing air not having passed through the vessel containing carbon dioxide absorbent into the cells; comparing the ratio of the light intensity measured in the first light intensity measuring step to the light intensity measured in the second light intensity measuring step with a threshold; and judging the absorption capacity of the carbon dioxide absorbent.</p> |
