For the determination of isotope ratios, the precision of TOF-ICP-MS has been studied in a preliminary comparison with other mass spectrometer systems [521]. Typical isotope ratio precisions of 0.05% were obtained, thus overtaking sector field mass spectrometry with sequential detection, for which values of 0.1-0.3% for 63Cu/65Cu in Antarctic snow samples have been reported [522], Similar results were obtained by Becker et al. [523] for Mg and Ca in biological samples (0.4-0.5%). In principle, the features of TOF-ICP-MS may be superior to those of sequential sector field or quadmpole mass spectrometry, however, true parallel detection of the signals as is possible with multicollector systems may be the defini-...

Inductively coupled plasma sector field mass spectrometry (ICP-SFMS) is used to identify and characterize radiation-producing particles found in soils that received fallout from the Chernobyl accident in 1986 [99]. ICP-SFMS provided sufficiently low detection limits for the analysis of plutonium isotopes found in soils along with high levels of other isotopes produced in nuclear reactions (i.e., fission products).

An even more powerful way to cope with spectral overlap is the use of an ICPMS instrument equipped with a double-focusing sector field mass spectrometer (inductively coupled plasma sector field mass spectrometry, ICP-SF-MS) instead of a quadrupole filter. By operating such a mass analyzer at higher mass resolution, the signal of analyte and interfering ions can be resolved in the majority of cases [33,34].

Glow discharge-sector field mass spectrometry (GD-SFMS) provides low limits of detection ( ng/g) and high mass resolution (up to 10,000) which helps to overcome problems due to molecular species formed in the plasma which can appear at the same nominal mass as the peaks of interest. Nevertheless, the fact that all GD-SFMS systems are sequential in nature is a serious limitation for the analysis of fast signals (e.g., depth profiling studies).

The development of modem sector field mass spectrometry, primarily driven by Nier [6], overlapped in time with these early advances in cosmochemistry and this enabled isotopic investigations to play a key role in cosmochemistry from the inception of the research field. Of particular initial importance was the age dating that could be achieved, based on the abundances of isotopes produced by long-lived radionuclides. The application of the U—Pb chronometer to establish the age of the Earth was pioneered by Houtermans and Holmes, using isotopic data originally acquired by Nier (7, 8]. More then a decade after these initial investigations. Patterson used a similar approach, but with refined methods and more suitable...
