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).

Exhaustive description of analysis:

Calculations: Δ¹⁷O = δ¹⁷O - 0.528 * δ¹⁸O
