The methods developed so far use either chemical conversion or isotope equilibration to determine the δ17 O value of CO2 .

The new technique is compared with the CO2 -O2 exchange method and the 17 O-correction algorithm for δ17 O and δ13 C values, respectively.RESULTS: The scale contractions for δ13 C and δ18 O values are slightly larger for fragment ion measurements than for molecular ion measurements. The δ17 O and Δ17 O values of CO2 can be measured on the 17 O+ fragment with an internal error that is a factor 1-2 above the counting statistics limit. The ultimate precision depends on the signal intensity and on the total time that the 17 O+ beam is monitored; a precision of 14 ppm (parts per million) (standard error of the mean) was achieved in 20 hours at the University of G{\"o}ttingen. The Δ17 O measurements with the O-fragment method agree with the CO2 -O2 exchange method over a range of Δ17 O values of -0.3 to + 0.7 ‰.CONCLUSIONS: Isotope measurements on atom fragment ions of CO2 can be used as alternative method to determine the carbon and oxygen isotopic composition of CO2 without chemical processing or corrections for mass interferences.",
