“…206 In this way the relative expanded uncertainties obtained with ID-TIMS were reduced to below 0.2% for the quantification of Cd, Cr, and Pb in polymer materials, where typical relative expanded uncertainties employing ID ICPMS range from 0.5% to 2%. 162 A further improvement was the application of triple IDMS to elemental analysis. 218 The major advantage of triple IDMS is that the isotope amount ratio of the spike does not need to be determined, as it is represented by a third blend in the IDMS equation.…”

“…159 This is an analytical task of importance as sulfur specifications are legislated by regulatory bodies for fossil fuels such as petrol and diesel because of environmental concerns. Due to its proven accuracy, TIMS has been employed for the certification of industrial relevant reference materials such as ''sulfur in petrol'' 160,161 and ''toxic elements in polymers'', 162 among others (see Section 14.4.7).…”

“…Additionally, lowest expanded uncertainties (o0.08%) can be obtained as demonstrated for the quantification of Cd in acrylonitrile-butadiene-styrene by ID TIMS. 162 Absolute Isotopic Composition, Atomic Weights and Isotope Reference Materials Along with some of the first instruments, TIMS has been used to determine the isotopic composition and from this the atomic weight of chemical elements. For some of the first atomic weight determinations, e.g.…”

The principle of TIMS is based on the formation of atom ions on a heated filament and the separation of these ions according to their mass/charge ratio in a mass spectrometer. In general, TIMS is applied for highprecision measurements of isotope ratios. In the basic design of a modern thermal ionisation source, a surface material is used in the shape of a flat ribbon filament. Usually, a solution (separated from the matrix and containing the element of interest in high concentration) is deposited in the centre of the filament as a liquid. Applying a current to the filament will evaporate and ionise the analyte deposited on the filament. In the case of a single-filament geometry, evaporation and ionisation of the analyte is accomplished with one filament, whereas in a double filament design, evaporation and ionisation is performed on two filaments placed parallel to each other. The analyte is evaporated on one filament, with ionisation occurring when the evaporated atoms strike the ionisation filament. A magnetic sector field is used as mass separator.

“…Two of them were prepared by the National Metrological Institute of Japan and have been reported (in Japanese) by Ohata and colleagues 240 and by Matsuyama et al 241 In the first of these reports, acrylonitrile butadiene styrene resin discs were manufactured and then analysed using EDXRF with no further sample preparation. 242 The procedures discussed included double isotope dilution mass spectrometry as well as TIMS and ICP-MS. The study reported the preparation and characterisation of four such resin disc CRMs that were given the numbers NMIJ CRM 8105a, NMIJ CRM 8106a, NMIJ CRM 8115a and NMIJ CRM 8116a.…”

“…The results obtained for the analytes Cd, Cr, Hg and Pb were compared with those obtained after a sample digestion procedure and analysis using ICP-MS and were found to be comparable. The problems associated with memory effects during the determination of Hg and of the dissolution of chromium(III) oxide were addressed in 242 Pu spike was added to the material before leaching with nitric acid. The second study described the preparation of polystyrene resin discs of dimensions 30 mm diameter by 2 mm thickness that contained decabrominated diphenyl ether.…”

Measurement uncertainty in single, double and triple isotope dilution mass spectrometry

Triple IDMS has been applied for the first time to the quantification of element concentrations. It has been compared with single and double IDMS obtained on the same sample set in order to evaluate the advantages and disadvantages of triple IDMS over single and double IDMS as an analytical reference procedure. The measurement results of single, double and triple IDMS are indistinguishable, considering rounding due to the individual measurement uncertainties. As expected, the relative expanded uncertainties (k = 2) achieved with double IDMS (0.08%) are dramatically smaller than those obtained with single IDMS (1.4%). Triple IDMS yields the smallest relative expanded uncertainties (k = 2, 0.077%) unfortunately at the expense of a much higher workload. Nevertheless triple IDMS has the huge advantage that the isotope ratio of the spike does not need to be determined. Elements with high memory effects, highly enriched spikes or highest metrological requirements may be typical applications for triple IDMS.
