“…Otherwise measured and thus mass discrimination affected data are mixed with "certified" not mass discrimination affected data. 53,56 Preferably in IDMS interferences are being separated, either by chemical [58] or by mass spectrometric means [59][60], as each correction causes an additional uncertainty and leaves the risk of incomplete correction.…”

This article describes the application of isotope dilution mass spectrometry (IDMS) to the field of reference material (RM) characterisation focusing on the approach, which is applied by the IDMS group at BAM. Emphasis is placed on IDMS measurements of highest analytical quality. Basic principles as well as the equation system are being recalled. Different calibration strategies, such as single, double or triple IDMS, are critically reviewed and the achievable uncertainties are discussed. Differences in the application of thermal ionization mass spectrometry (TIMS) and inductively coupled plasma mass spectrometry (ICPMS) are discussed as well as differences between different types of mass spectrometers such as single collector versus multi-collector or quadrupole versus magnetic sector instruments. Possible sources of errors and bias are mentioned and correction models introduced and applied within the past years are discussed. Several examples for RM characterisations in the field of elemental analysis are shown, each demonstrating excellent analytical quality. In general it can be stated that IDMS is the most important reference method for elemental analysis, offering highest accuracy and precision or smallest measurement uncertainties, when properly applied. Thus IDMS represents by far the best suited reference method for RM characterisation. Due to its universal applicability IDMS offers sufficient potential to follow future needs in analytical chemistry as well as in the RM sector.

“…Evans et al reported on highaccuracy analysis of sulfur in diesel fuel by the isotope dilution technique. 95 To an increasing extent the isotope dilution technique has been being applied in the certification of reference materials, e.g., of Hg in polyethylene certified reference materials (CRM 680 and 681), or Cd and Tl in high-purity Zn (CRM 325/2R). ID-ICP-MS has yielded the most accurate data, as demonstrated recently by Vogl.…”

The capability to determine isotope abundances is a main feature of mass spectrometry. The precise and accurate determination of isotope ratios is required for different application fields, such as: isotope ratio measurements of stable isotopes in nature, especially for the investigation of isotope variation in nature or age dating; determining isotope ratios of radiogenic elements in the nuclear industry; quality assurance of fuel material for reprocessing plants, nuclear material accounting and radioactive waste control; and tracer experiments using highly enriched stable isotopes or long-lived radionuclides in biological or medical studies. Inductively coupled plasma mass spectrometry and laser ablation ICP-MS (LA-ICP-MS) provides excellent sensitivity, precision and good accuracy for isotope ratio measurements with practically no restriction with respect to the ionization potential of the element investigated. Therefore both ICP-MS and LA-ICP-MS are increasingly replacing thermal ionization mass spectrometry (TIMS), which has been used as the dominant analytical technique for precise isotope ratio measurements for many decades. In the last few years instrumental progress for improving figures of merit in isotope ratio measurements in ICP-MS and LA-ICP-MS with a single ion detector has been achieved by the introduction of the collision cell interface, in order to dissociate disturbing argon-based molecular ions, to reduce the kinetic energy of ions and neutralize the disturbing argon ions of the plasma gas (Ar 1 ). The application of the collision cell in ICP-MS results in higher ion transmission, improved sensitivity and better precision of isotope ratio measurements compared to ICP-MS without the collision cell. The most important instrumental improvement for isotope analysis by sector field ICP-MS was the application of a multiple ion collector device (MC-ICP-MS) (developed about 10 years ago) in order to obtain better precision of isotope ratio measurements of up to 0.002%, RSD.

“…Measurement of S isotopes by single-collector ICP-MS is obtained sequentially and vriability of plasma conditions (e.g., efficiency of ionization, ion beam extraction) can significantly degrade the measurement of isotope ratios. The overall precision achievable by this method is typically greater than 2 to 5 ‰ (Jarvis et al, 1992;Menegário et al, 1998;Evans et al, 2001) and is not sufficient to resolve all sulfur isotope variations occurring in nature. The introduction of multiple collector ICP-MS technology has enabled simultaneous measurement of multiple isotopes, providing precise and rapid isotope ratio determination.…”

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.
