Development of hydrocarbon gas standards for stable isotopic composition (δ13C and δ2H)
A suite of gas standards was developed to serve as international secondary reference materials (RMs) for the determination of the compound-specific carbon-13/carbon-12 (δ13C) and hydrogen-2/hydrogen-1 (δ2H) values of hydrocarbon gases. This report provides background information on the project, the methods used to produce and analyze the gases, as well as the data analysis and recommended stable i
