ISOTOPIC GAS ANALYZER AND METHOD OF JUDGING ABSORPTION CAPACITY OF CARBON DIOXIDE ABSORBENT

摘要

In an isotopic gas analyzer, a gas injector (21) is provided for pressurizin g a gas specimen in cells (11a,11b). The pressurization of the gas specimen virtually produces the same effect as increasing the concentration of carbon dioxide in the gas specimen, thereby improving an S/N ratio for the analysis and hence data reproducibility.
