Hi all,
We need to know the 18O from the CO2 of reference material NGS2 NIST Gas.
We need to set a procedure to measure the 18O from CO2 of natural gas
samples by GC/C IRMS (GCCIII & MAT252). We need to establish the 18O of our
CO2 LabTank reference gas under GC conditions for natural gas. I hope not
to face interferences under mass 46. I would be glad to hear your opinion.
