Hello everybody, I am going to make a question that I
know it has the risk of being very stupid. Is it
possible to quantify (or at least estimate) the amount
of DIC in a water sample, analyzed using a Gas Bench
and Delta XP, using the chromatogram generated by
Isodat as a basis (of course, a standard with known
DIC concentrationi would be measured too, and
precautions to use a precise sample volume, etc)?
I am making this question because when running a few
samples, the difference between the peak height of
some samples was very marked, which to me suggests the
possibility of quantification.

Thank you for any help,
