Methods & Sampling

Methodology:

Sampling and analytical procedures:

Using the lab experiment data in the dataset “Incidence of volume effect with the denitrifier method”, ẟ15N (ẟ18O) scale contraction was calculated as the percent deviation of the difference between measured ẟ15N (ẟ18O) values of IAEA-NO3 and USGS-34 from the true difference.
