“…[23] However integration times of 40 to 100 s for a single replicate are not appropriate for transient laser ablation signals, and the background spectra shown by Resano et al shows a large background elevation and depletion from the baseline, which could affect the elements of interest (e.g., Mg, Si and Fe). [24] In contrast, MC-ICP-MS is suited for high-precision isotope ratio analysis and can be combined with simultaneous element analysis. In static mode, the limited mass range covered by the multicollector array allows the simultaneous measurement of only a small number of elements (e.g., 23 Na up to 26 Mg, 27 Al with 30 Si).…”

. (2016) Si) on the micrometre scale in geological samples. In both routines, multicollector inductively coupled plasma mass spectrometry (MC-ICP-MS) is combined with femtosecond-LA, where stable isotope ratios are corrected for mass bias using standard-sample-bracketing with matrix-independent calibration. The first method is based on laser ablation split stream (LASS), where the laser aerosol is split and introduced simultaneously into both the MC-ICP-MS and a quadrupole ICP-MS. The second method is based on optical emission spectroscopy using direct observation of the MC-ICP-MS plasma (LA-MC-ICP-MS|OES). Both methods are evaluated using international geological reference materials. Accurate and precise Si isotope ratios were obtained with an uncertainty typically better than 0.23 ‰, 2SD, δ 30Si. With both methods major element concentrations (e.g., Na, Al, Si, Mg, Ca) can be simultaneously determined. However, LASS-ICP-MS is superior over LA-MC-ICP-MS|OES, which is limited by its lower sensitivity. Moreover, LASS-ICP-MS offers trace element analysis down to the µg g -1 -range for more than 28 elements due to lower limits of detection, and with typical uncertainties better than 15%. For in situ simultaneous stable isotope measurement and chemical composition analysis LASS-ICP-MS in combination with MC-ICP-MS is the method of choice.Keywords femtosecond laser ablation, inductively coupled plasma multicollector mass spectrometry, split stream, optical emission spectroscopy, stable silicon isotope ratios

“…With a sensitivity similar to most of the quadrupole ICP‐MS instruments, the Spectro ICP‐MS seems well suited for common geoscience applications (e.g., Resano et al . ). However, the potential advantage of the fast data acquisition for detection of transient signals by this Mattauch‐Herzog ICP‐MS remains to be tested more thoroughly, because dumping of the accumulated charge from the individual channels may slow the detector response.…”

Advances in the chemical and isotopic characterisation of geological and environmental materials can often be ascribed to technological improvements in analytical hardware. Equally, the creation of novel methods of data acquisition and interpretation, including access to better reference materials, can also be crucial components enabling important breakthroughs. This biennial review highlights key advances in either instrumentation or data acquisition and treatment, which have appeared since January 2010. This review is based on the assessments by scientists prominent in each of the given analytical fields; it is not intended as an exhaustive summary, but rather provides insight from experts of the most significant advances and trends in their given field of expertise. In contrast to earlier reviews, this presentation has been formulated into a unified work, providing a single source covering a broad spectrum of geoanalytical techniques. Additionally, some themes that were not previously emphasised, in particular thermal ionisation mass spectrometry, accelerator‐based methods and vibrational spectroscopy, are also presented in detail.

“…437 Resano et al demonstrated the applicability of a new Mattauch-Herzog instrument coupled to a laser-ablation system for the direct simultaneous determination of platinum-group elements in NiS buttons prepared from ores. 438 Apart from the apparent application of isotopic analysis of radioactive and radiogenic nuclides for geochronology, isotope ratios involving natural and artificial long-lived radionuclide have been used as a tool in numerous other areas, ranging from environmental monitoring and nuclear safeguards to the nuclear industry and nuclear waste control. The related analytical tasks are often tackled using mass-spectrometric techniques, as Becker described in a comprehensive review on the topic.…”

ICP-MS is based on the formation of (preferentially monovalent positively) charged atomic ions in an inductively coupled Ar plasma at almost 10 000 K. The ions formed are transferred from the plasma source at ambient pressure into a mass separator operated at high vacuum via a set of cones. The ions are separated according to their mass/charge ratio in the mass separator (quadrupole, magnetic sector field or time-of-flight mass separator). In most cases, the ions are detected using a secondary electron multiplier; in some set-ups (also) a Faraday cup can be used. Single-collector (scanning mass spectrometer usually used for quantitative elemental analysis) or multicollector (static operation of mass spectrometer for precise isotope ratio analysis) configurations can be found (Figures 12.1 and 12.2).
