“…A much more detailed picture is obtained by determining multielement and multitraceelement compositions by ICP MS. It is a well‐established technique applied in many diverse fields such as environmental science,39, 40 geology,41 pharmaceutical and biomedical sciences,42 bioinorganic analysis1 and forensic investigations,43 among many others. Elemental compositions are used not only to characterize and judge the quality aspects of a sample but are also often used to diagnose processes or reveal the history of the sample.…”

Inductively coupled plasma (ICP) mass spectrometry (MS) is routinely used in many diverse research fields such as earth, environmental, life and forensic sciences and in food, material, chemical, semiconductor and nuclear industries. The high ion density and the high temperature in a plasma provide an ideal atomizer and element ionizer for all types of samples and matrices introduced by a variety of specialized devices. Outstanding properties such as high sensitivity (ppt-ppq), relative salt tolerance, compound-independent element response and highest quantitation accuracy lead to the unchallenged performance of ICP MS in efficiently detecting, identifying and reliably quantifying trace elements. The increasing availability of relevant reference compounds and high separation selectivity extend the molecular identification capability of ICP MS hyphenated to species-specific separation techniques. While molecular ion source MS is specialized in determining the structure of unknown molecules, ICP MS is an efficient and highly sensitive tool for target-element orientated discoveries of relevant and unknown compounds. This specialfeature, tutorial article presents the principle and advantages of ICP MS, highlighting these using examples from recently published investigations.

“…The importance of PGE has grown over the last years, notably because of environmental pollution associated with their incorporation in automobile catalytic converters (Linge 2005). The road dust reference material BCR-723 and the auto catalyst NIST SRM 2557 seem to be suitable samples for such investigations, where certified values of Pd, Pt and Rh are available.…”

This review gives an overview of the use and development of reference materials of geochemical and environmental interest in the literature of the years 2004 and 2005. In these years the performance of existing methods has been improved and new geochemical applications using new techniques have been developed. Accordingly, there was an increasing need for new reference materials, especially for in situ microanalysis and for precise stable isotope measurements. In addition, there was a notable trend for further characterisation of existing reference materials, mainly for the platinum‐group elements. This review focuses on five topics: reference materials for platinum‐group elements, reference glasses for in situ microanalysis, zircon reference materials, isotopic reference materials, and the development and certification of reference materials.

“…[12][13][14][15] Although SIMS and laser ablation are increasingly used, hand drilling and micromilling remain the most commonly used sampling methods, 11,16 due to their balance of accessibility, precision and resolution, and because they produce the powdered samples necessary for high-precision MC-ICPMS (Multicollector Inductively Coupled Plasma Mass Spectrometry) and ICP-AES (Inductively Coupled Plasma Atomic Emission Spectroscopy). [17][18][19] Micromilling provides the opportunity to precisely mill from very specific regions of the sample and at high resolution, but is more time consuming than hand drilling and the equipment is often temperamental. The collection of micromilled powder samples is most commonly accomplished manually using a combination of scalpels and razor blades, 16 so the process requires a flat and relatively wide sampling surface.…”

Rationale Embedding resins are commonly used to facilitate high‐resolution sampling for stable isotope analysis but anomalous δ13C values have been observed in some cases. Here we compare the results of microsampling strategies for hand‐drilled versus resin‐embedded micromilled samples from the same marine shells to assess whether resin contamination is implicated in δ13C spikes. The comparison allows assessment of the relative benefits for spatial resolution, seasonal range for both δ18O and δ13C, and sample failure rates. Methods Hand‐drilled samples were obtained from two bivalve shells (Spisula sachalinensis), corresponding to micromilled samples on the same shells where high δ13C spikes were observed. All carbonate powders were analysed using a dual‐inlet Isoprime mass spectrometer and Multiprep device. Results from both sample sets were compared statistically. Results No anomalous high δ13C values and no failures due to insufficient gas were observed in the hand‐drilled samples in contrast to the embedded micromilled sequences. Spatial resolution was reduced (~2.5×) in the former compared with the latter, resulting in a small reduction in the total range observed in the micromilled δ13C and δ18O values. Reduced sampling resolution between the two datasets was only significant for δ18O. Conclusions For S. sachalinensis (as with other similar bivalves), rapid growth mitigates the reduced sampling resolution of hand drilling and does not significantly impact observed isotopic range and seasonal patterning. Occurrence of anomalous δ13C values were eliminated and failure rates due to insufficient sample size greatly reduced in the hand‐drilled dataset. We can find no other explanation for the occurrence of δ13C spikes than contamination by the embedding agent. We conclude that the logistical and interpretational benefits of careful hand drilling may be preferable to resin embedding for micromilling in marine shells, corals or speleothems where growth rate is rapid and the highest resolution is not required.
