“…Instrumental mass bias within ICP-MS results from so-called 'space-charge' and 'ion-diffusion' effects on the transmission of ionized particles (Tanner, 1992;Vanhaecke et al, 1993;Maréchal et al, 1999) and has been shown to be sensitive to matrix composition (Galy et al, 2003;Pietruszka et al, 2006). In order to evaluate the possibility of matrix effects from elements that are commonly found in sulfide and sulfate minerals, we performed doping experiments using S spex standard solution mixed with various high-purity element solutions.…”

isotope compositions are best determined using purified (matrix-clean) sulfur standards and sample solutions using the chemical purification protocol we present. For in situ analysis, where the complex matrix cannot be removed prior to analysis, appropriately matrix-matching standards and samples removes matrix artifacts and yields sulfur isotope ratios consistent with conventional techniques using matrix-clean analytes. Our method enables solid samples to be calibrated against aqueous standards; a consideration that is important when certified, isotopically-homogeneous and appropriately matrix-matched solid standards do not exist.Further, bulk and in situ analyses can be performed interchangeably in a single analytical session because the instrumental setup is identical for both. We validated the robustness of our analytical method through multiple isotope analyses of a range of reference materials and have compared these with isotope ratios determined using independent techniques. Long-term reproducibility of S isotope compositions is typically 0.20 ‰ and 0.45 ‰ (2σ) for solution and laser analysis, respectively. Our method affords the opportunity to make accurate and relatively precise S isotope measurement for a wide range of sulfur-bearing materials, and is particularly appropriate for geologic samples with complex matrix and for which high-resolution in situ analysis is critical.

“…Stable isotope-ratio measurements using MC-ICP-MS have recently found a wider interest [206,[208][209][210][211]. While all isotopes can be used for stable isotope studies, subtle isotopic variations require an uncertainty of better than 0.1 ‰ using the R( 74 Ge/ 70 Ge) ratio; both isotopes have a relatively high abundance, and they exhibit the largest atomic mass difference.…”

“…Lead has four stable isotopes, 204 Pb, 206 Pb, 207 Pb, and 208 Pb, with isotopic abundances of 1.4, 24.1, 22.1, and 52.3 %, respectively, in naturally occurring terrestrial material. Only 204 Pb is primordial; the three heavier isotopes are radiogenic.…”

Abstract:Since the early 1950s, the number of international measurement standards for anchoring stable isotope delta scales has mushroomed from 3 to more than 30, expanding to more than 25 chemical elements. With the development of new instrumentation, along with new and improved measurement procedures for studying naturally occurring isotopic abundance variations in natural and technical samples, the number of internationally distributed, secondary isotopic reference materials with a specified delta value has blossomed in the last six decades to more than 150 materials. More than half of these isotopic reference materials were produced for isotope-delta measurements of seven elements: H, Li, B, C, N, O, and S. The number of isotopic reference materials for other, heavier elements has grown considerably over the last decade. Nevertheless, even primary international measurement standards for isotope-delta measurements are still needed for some elements, including Mg, Fe, Te, Sb, Mo, and Ge. It is recommended that authors publish the delta values of internationally distributed, secondary isotopic reference materials that were used for anchoring their measurement results to the respective primary stable isotope scale.

“…In addition to its high mass resolution and high sensitivity, its unique flat topped peaks produced in low resolution mode provide for a more accurate and precise isotope ratio measurement. [7][8][9][10][11] This has been reported to be better than 0.04% precision with a single detector and as low as 0.002% on instruments equipped with a multi-collector detector.…”

Using gas chromatography (GC) for sample introduction and analyte separation, a performance comparison was made between sector field inductively coupled plasma mass spectrometry (SF-ICP-MS) detection and quadrupole ICP-MS (qICP-MS) detection. Samples were extracted with acetic acid using open microwave digestion, derivatized with sodium tetraethylborate and extracted into isooctane. Mass bias correction was implemented based on the expected ratio of 120 Sn/ 117 Sn to that of the mean 120 Sn/ 117 Sn ratio calculated from the inorganic Sn peaks detected in all chromatograms. A more than 2-fold improvement in precision of calculated 120 Sn/ 117 Sn ratios was obtained for both TBT and DBT in stan...
