Dear Members,
I am running a Fisons NA 1500 EA with a Finnigan Delta S MS for CF IRMS analysis of N15. I am curious if anyone has had problems with samples with large amounts of carbon in relation to the nitrogen content as would occur in plant samples, i.e. 2-3% N, 40% C. What was your solution to the problem?
Thanks,
