Zirconium isotopic composition of zircon reference materials by laser ablation multi-collector inductively coupled plasma mass spectrometry

A community-led calibration of the Zr isotope reference materials: NIST candidate RM 8299 and SRM 3169

“…Because of the rapid expansion of the Zr isotope system, multiple Zr isotope standards have been proposed, in particular for the characterization of mass-dependent effects, such as the SRM 3169 (ref. 26, 29–35), the candidate RM 8299 presented herein, 7–9,11,12,36–38 a single-element Zr solution from PlasmaCal (SCP Science) also known as the IPGP-Zr standard, 5,6,10,11,30,33,35,38–46 and the NRC ZIRC-1 (ref. 44, 47 and 48).…”

“…aWhile homogeneity should be ensured by the fact that this proposed RM exist in solution form, to the best of our knowledge, no bottle-to-bottle isotopic homogeneity study has been performed.bIncluding 16 publications focused on mass-dependent isotope effects (ref. 7–9, 11, 12, 26, 29–38), and 10 focused on mass-independent effects (ref. 13, 15–23).…”
