Emphasis is placed on liquid and solid RMs and IDMS measurements of the highest analytical quality. Basic principles, as well as the equation system, are being revisited. 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 (ICP-MS) 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 and inter-laboratory comparisons for elemental as well as elemental species analysis are shown, each demonstrating excellent analytical quality. In general, it can be stated that IDMS is the most important reference method for elemental and elemental species analysis, offering the highest accuracy and precision or smallest measurement uncertainties, when properly applied. Thus, IDMS represents by far the best suited reference method for RM characterisation. Owing to its universal applicability IDMS offers sufficient potential to follow future needs in analytical chemistry as well as in the RM sector.

T1 - Production of three certified reference materials for the sulfur content in gasoline (petrol) N2 - Directive 2003/17/EC of the European Parliament and the European Council stipulates that petrol (gasoline) with a total sulfur content below 10 mg kg-1 must be available in all European Union member states by 2009. Three certified reference materials were produced in support of this directive in a joint effort of the members of the European Reference Materials Initiative (ERM). Two of the materials were made from commercial petrol, while the third one was prepared from a blend of commercial petrols. Relative between-ampule heterogeneity of the materials was quantified and found to be below 2.5%. Potential degradation during storage and dispatch was quantified, and shelf lives based on these values were set. The three materials were characterized by three institutes using different variants of isotope-dilution mass spectrometry. The results from the three institutes were combined, and the final uncertainties of the respective sulfur mass fractions were estimated including contributions from heterogeneity, stability, and characterization. The following mass fractions were derived: ERM-EF211, 48.8 ± 1.7 mg kg-1; ERM-EF212, 20.2 ± 1.1 mg kg-1; and ERM-EF213, 9.1 ± 0.8 mg kg-1.

In contrast to the huge analytical progress in isotope ratio analytics, the production of isotope reference materials has not kept pace with the increasing needs of isotope analysts. Three representative isotope systems are used to explain the technical and non-technical difficulties and drawbacks, on one hand, and to demonstrate what can be achieved at its best, on the other hand. A clear statement is given that new isotope reference materials are needed to obtain traceable and thus comparable data, which is essential for all kinds of isotope research. The range of available isotope reference materials and δ reference materials should be increased and matrix reference materials certified for isotope compositions or δ values, which do not exist yet, should be provided.

A1 - Koenig, Maren A1 - Pritzkow, Wolfgang T1 - A modified lead-matrix separation procedure shown for lead isotope analysis in Trojan silver artefacts as an example N2 - A modified Pb–matrix separation procedure using NH4HCO3 solution as eluent has been developed and validated for determination of Pb isotope amount ratios by thermal ionization mass spectrometry. The procedure is based on chromatographic separation using the Pb·Spec resin and an in-house-prepared NH4HCO3 solution serving as eluent. The advantages of this eluent are low Pb blanks (<40 pgmL-1) and the property that NH4HCO3 can be easily removed by use of a heating step (>60 °C). Pb recovery is >95 % for water samples. For archaeological silver samples, however, the Pb recovery is reduced to approximately 50 %, but causes no bias in the determination of Pb isotope amount ratios. The validated procedure was used to determine lead isotope amount ratios in Trojan silver artefacts with expanded uncertainties (k=2) <0.09 %.
