“…Isotope ratio measurements for a range of organolead compounds (trimethyl lead, dimethyl lead, triethyl lead, diethyl lead and inorganic lead) by GC-ICP-QMS using a quadrupole ICP-MS (HP 4500) were described recently by Encinar et al 85 An analytical method for the measurement of high-precision isotope ratios of mercury in coals using transient signals was developed recently by Evans et al 86 Hg (1 ng) was loaded onto a gold trap. The Hg in coal was released by pyrolysis at 1200 uC.…”

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.

“…In order to avoid so-called spectral skew, which describes the peak shape deterioration and apparent shift on different isotopes, 203 as illustrated in Figure 7.14, the number of isotopes measured, the dwell time per isotope and the chromatographic separation conditions have to be carefully balanced. Long dwell times provide the advantage of improved signal-to-noise ratios, but will induce poorer peak definition, while very short dwell times provide good peak definition, but suffer from higher signal noise.…”

“…Those peaks were assigned according to reports. 22,23 When the isotope dilution technique is applied to a solid sample, the extraction efficiency of analytes from the sample can significantly affect the analytical results. 24 Thus, we investigated the effects of the extracting time on the analytical results.…”

“…11,22,25 The measurement precision of TML was much better in this work than those of the literature values, since the extraction time was relatively long compared with those in the mentioned reports. 11,[22][23][24][25] The TEL in BCR 605 was first determined. The measurement variation was rather small at such a low concentration level.…”
