There are major problems in determining CO/sub 2/ in pure inorganic gases on account of difficulties in making and storing standard specimens with low impurity contents. A combined isotopic, chromatographic, and spectral method can be employed based on cryogenic adsorption, which in principle allows one to determine low values of minor components without using such specimens. The method is used in this paper to determine CO/sub 2/ in pure inorganic gases: He, Ne, Ar, N/sub 2/, and H/sub 2/. The method includes the following steps: gas sampling; adding a known amount of carbon dioxide enriched in /sup 18/O; physicochemical transformation of the resulting analytical mixture (AM); and spectroscopic derivation of the isotope ratio c/sub C/sup 16/O/sub 3///c/sub C/sup 18/O/sub 2// = c/sub 1//c/sub 2/, with calculation of the unknown content c/sub x/ in mole %.
