摘要：A method for producing standard gases CO and H<SB>2</SB> for the analysis of hydrogen and oxygen isotopes comprises decomposing, preferably by heat, in a reactor initial products ie. carbon dioxide and alkanes, to produce CO and H<SB>2</SB>, respectively which are subsequently fed to a mass spectrometer. The method improves the safety of the operation insofar as the initial feed products are less toxic and combustible than CO and H<SB>2</SB>.
