In an isotopic gas analyzer, a gas injector (21) is provided for pressurizing 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.
Selon l'invention, dans un analyseur de gaz isotopique, un injecteur de gaz (21) permet de comprimer un échantillon gazeux dans des cellules (11a, 11b). La compression dudit échantillon produit pratiquement le même effet que le fait d'augmenter sa teneur en dioxyde de carbone, ce qui améliore un rapport S/N de l'analyse et, par conséquent, la reproductibilité des données.
