Abstract
In an isotopic gas analyzer, a gas injector () is provided for pressurizing a gas specimen in cells (). 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.
