Enabling scientific discovery through stable isotope analysis
Analysis of Sulfate & Nitrate Δ17O
Summary: We use a TC/EA to thermally degrade NO3- or SO42- to NO and O2 or SO2 and O2. The O2 is then passed to a Finnigan MAT253 for δ18O and δ17O analysis.

Reference Materials: We use USGS35 and IAEA-NO-3 as our international standards.
