“…Compared to the radiogenic abundance alterations, the mass-dependent fractionation changes are small, of the order of 1 ‰ [312]. The IRMM has made an attempt to produce calibration reference materials explicitly for lead isotope-δ measurements ("δ-iCRM") [307] with ERM-3800 proposed as the zero-delta material. With these materials used as references in MC-ICP-MS direct comparisons, an uncertainty between 0.01 and 0.05 ‰ has been achieved [308].…”

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.

“…ERM‐3800 and the ERM‐3810 series were produced in 2009 for delta measurements (Ponzevera et al . ), but are not yet available. In 2011, NIM China released the iCRM GBW‐04442 (NIM ), which is enriched in 207 Pb and intended to be used as spike material in isotope dilution mass spectrometry.…”

Lead isotope amount ratios are commonly used in diverse fields such as archaeometry, geochemistry and forensic science. Currently, five reference materials with certified lead isotope amount ratios are available, namely NIST SRM 981, 982 and 983, GBW-04442 and NMIJ 3681-a. Only NIST SRM 981 and NMIJ 3681-a have approximately natural isotopic compositions, and NIST SRM 981 is predominantly used for correcting mass discrimination/mass fractionation in the applied mass spectrometric procedures. Consequently, there is no other certified reference material available to be used for validation and/or quality control of the analytical procedures applied to lead isotope amount ratio measurements. To fill this gap, two new reference materials have been produced and certified for their lead isotope amount ratios. For both certified reference materials, complete uncertainty budgets have been calculated and SI traceability has been established. This provides the users with independent means for validating and verifying their analytical procedures and for conducting quality control measures. ERM-EB400 is a bronze material with a nominal lead mass fraction of 45 mg kg -1 and certified lead isotope amount ratios of n( 206 Pb)/n( 204 Pb) = 18.072(17) mol mol -1 , n( 207 Pb)/n( 204 Pb) = 15.578 (18) mol mol -1 and n( 208 Pb)/n( 204 Pb) = 38.075(46) mol mol -1 with the associated expanded uncertainties (k = 2) given in brackets. ERM-AE142 is a high-purity solution of lead in 2% nitric acid with a nominal mass fraction of 100 mg kg -1 and certified Pb isotope amount ratios of n( 206 Pb)/n( 204 Pb) = 21.114(17) mol mol -1 , n( 207 Pb)/ n( 204 Pb) = 15.944(17) mol mol -1 and n( 208 Pb)/n( 204 Pb) = 39.850(44) mol mol -1 with the associated expanded uncertainties (k = 2) given in brackets. Both materials are specifically designed to fall within the natural lead isotopic variation and to assist users with the validation and verification of their analytical procedures. Note that while one of these reference materials requires the chemical separation of Pb from its matrix (ERM-EB400), the other does not (ERM-AE142). As additional information, d 208/206 Pb NIST SRM981 values are provided for both materials. For ERM-AE142, a delta value of d 208/206 Pb NIST SRM981 = -28.21(30)‰ was obtained, and for ERM-EB400, a delta value of d 208/206 Pb NIST SRM981 = -129.47(38)‰ was obtained, with the associated expanded uncertainties (k = 2) given in brackets.

“…A detailed description of the way the candidate ERM-3810 series was produced can be found elsewhere. 24 In brief, these materials are available in quartz ampoules as 2 mL of 100 mg g À1 Pb solutions. Fortification with 207 Pb was achieved gravimetrically from $ 10 mg Pb g À1 solutions, originating from the dissolution of weighed amounts of pure solid Pb materials.…”

“…IRMM has produced by gravimetric mixing a series of a new type of Pb isotopic Certified Reference Materials, described as d-iCRMs, which may be used to validate methods developed for d-scale isotopic measurements. 24 These comprise four pairs of ampoules containing natural-like Pb (candidate ERM-3800) in one and the same natural Pb material progressively enriched in 207 Pb (candidate ERM-3810 series) in the others, producing d 207 Pb values ranging from $0.01& to $0.1&, certified to $ 0.1% relative uncertainty (k ¼ 2).…”
