Overview

Validation study demonstrates efficient single-step separation of calcium, strontium, and rare earth elements from single samples, indicating improved accessibility for isotopic bioarchaeology.

Key Points

  • Develop and validate a simplified, non-automated chromatographic protocol using DGA resin to sequentially separate calcium, strontium, and rare earth elements from a single sample aliquot.
  • Designed a manual, single-column chromatographic protocol using reusable DGA resin and a limited selection of acids.
  • Validated the separation procedure using six certified reference materials encompassing both organic and inorganic matrices (N=6).
  • Achieved efficient, reproducible chromatographic separation of matrix elements, calcium, strontium, and rare earth elements with quantitative elemental recoveries and minimal cross-contamination.
  • Produced δ44Ca/42Ca, δ88Sr/86Sr, and 87Sr/86Sr isotope ratios that closely matched published certified values across all reference standards.
