By using the experimental design (DoE) technique, we optimized an analytical method for the determination of mercury isotope ratios by means of cold-vapor multicollector ICP-MS (CV-MC-ICP-MS) to provide absolute Hg isotopic ratio measurements with a suitable internal precision.
The TIMS analyses demonstrate that each of these minerals, with the possible exception of Durango apatite, is more homogeneous in Nd isotopic composition than can be measured based upon the internal precision of the LA-MC-ICPMS analyses in this study.
