TY  - JOUR
AB  - Precise and accurate δ66/64Zn data for environmental reference materials (RMs) including rocks,sediments, soils and plants are presented in order to improve the metrological traceability andanalytical control of Zn isotope ratio determinations in future environmental studies. Previouslydeveloped ion exchange chromatography protocols were adjusted to enable faster sample throughputand instrumental mass bias processes were investigated. The improved chromatographic protocolyielded precise and quantitative recoveries (99 ± 7%, σ, n = 16), while the mass bias correctionusing Cu as external dopant provided precisions better than 0.02‰, 2σ, n = 7. Investigations intospectral and non-spectral interferences identified significant formation of Cr and Ti oxides andhydroxide ionic species. Analysis of six RMs (BHVO-2 basalt (USGS), BCR-2 basalt (USGS),AGV-2 andesite (USGS), 2709 San Joaquin soil (NIST), 1646a estuarine sediment (NIST) and1573a tomato leaves (NIST)) showed good reproducibility (< 0.01‰, 2σ, 5 ≤ n ≥ 1).
