Fluorination of Silver Phosphate in Nickel Reaction Vessels for Triple Oxygen Isotope Analysis
We report the δ<sup>17</sup>O, δ<sup>18</sup>O, and Δ'<sup>17</sup>O values for a large suite of silver phosphate standards and present two new standards that can be used for interlaboratory calibration. Our results are reported on the VSMOW2-SLAP2 scale by measuring silicates on the same instrument with the same reference gas. The fluorination method in nickel reaction vessels is easily adapted to other laboratories that have fluorination lines. Only 2-3 mg of silver phosphate is needed for Δ'<sup>17</sup>O measurements when paired with δ<sup>18</sup>O values using the TC-EA technique.
