New Ag₃ PO₄ comparison material for stable oxygen isotope analysis.

ABSTRACT:

Rationale

A silver phosphate reference material (Ag₃ PO₄ ) for the measurement of stable oxygen isotope compositions is much needed; however, it is not available from the authorities distributing reference materials. This study aims to fill this gap by calibrating a new Ag₃ PO₄ stable isotope comparison material produced by the University of Natural Resources and Life Sciences (BOKU).

Methods

Aliquots of Ag₃ PO₄ were distributed to four laboratories who frequently measure the δ¹⁸ O value in Ag₃ PO₄ ; the University of Natural Resources and Life Sciences (BOKU), the University of Western Australia (UWA), the University of Helsinki (UH), and the Helmholtz Centre for Environmental
