Enabling scientific discovery through stable isotope analysis
Analysis of Nitrate Δ17O
Summary: We use a silver salt pyrolysis method in a TC/EA coupled to a Thermo MAT253 for a continuous flow based analysis of nitrate δ17O and δ18O.

Reference Materials: We use USGS35 and an internal mass dependent nitrate to calibrate this method.

Sample submission: If you are interested in submitting samples for this type of analysis, please contact us using the contacts below. Please include in your shipment container the following form (pdf or doc).
