Isogeochemists,
I havefound the reference of the paper on a mass spectrometric
correction for the presence of N2O when measuring 18 O in CO2. It is
Friedli & Siegenthaler (1988) Influence of N2O on isotope analyses in
CO2 and mass-spectrometric determination of N2O in air samples.
Tellus, 40 B, 129 - 133.
As K. Revesz pointed out to me, there is of course gas cromatography
to solve the problem in a very elegant manner:
Anal. Chem. (1990), 62, 972 - 973.
