Guidelines for Accurate and Precise Stable Isotope Analysis of Calcite, Dolomite, and Magnesite Using a Carbonate Device for Continuous Flow‐Isotope Ratio Mass Spectrometry (CF‐IRMS)
To determine precise and accurate δ<sup>13</sup>C and δ<sup>18</sup>O values of a carbonate mineral using the carbonate-phosphoric acid reaction method, an optimal reaction time must be assessed for a given analytical condition to avoid nonequilibrium isotope effects and unnecessary oxygen isotope exchange of acid-liberated CO<sub>2</sub> in the carbonate reaction vessel. Our experimental result provides a guideline for the accurate and precise stable isotope analysis of Ca-Mg carbonate minerals.
