“…The most common terms for this are Trace Element AMS (TEAMS, e.g., Wallner et al . ) or if the Cs beam is focused and spatial resolution kept, Accelerator‐SIMS or Super‐SIMS (Matteson ). However, mainly due to the background from the ion source, detection limits are not as low for Super‐SIMS as for ‘standard’ AMS, but still some orders of magnitude better than is the case for traditional dynamic SIMS.…”

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.

“…27 to produce negatively charged secondary carbon ions (C À ). 2 The use of sputtered Cs + eliminates atomic isobaric interference from 14 N because anionic 14 N À is physically and chemically very unstable. 10,28 The beam of C À ions enters the injection magnet where the ions are separated by mass to charge (m/z) ratio, thus segregating 12 C, 13 C, and 14 C ions.…”

“…Accelerator mass spectrometry (AMS) is the ultimate technique for measuring various long-lived isotopes as well as trace stable isotopes in small amounts of sample. 1,2 Conventional mass spectrometry (MS) can be used to determine various isotopes in samples of interest but cannot accurately measure isotopes such as 14 C with low natural abundance owing to detection limits and isobaric interferences. [3][4][5][6] Unlike conventional MS, AMS directly counts and measures individual isotopes in samples of interest, increasing the efficiency and minimizing the required sample size.…”

Accelerator mass spectrometry (AMS) is the ultimate technique for measuring rare isotopes in small samples. Biological and biomedical applications of (14)C-AMS (bio-(14)C-AMS) commenced in the early 1990s and are now widely used in many research fields including pharmacology, toxicology, food, and nutrition. For accurate, precise, and reproducible bio-(14)C-AMS analysis, the graphitization step in sample preparation is the most critical step. So, various sample preparation methods for a process called graphitization have been reported for specific applications. Catalytic graphitization using either a flame-sealed borosilicate tube or a septa-sealed vial is a popular sample preparation method for bio-(14)C-AMS. In this review, we introduce the AMS system, especially for bio-(14)C-AMS. In addition, we also review the graphitization method for bio-(14)C-AMS to promote further understanding and improvement of sample preparation for this technique. Examples of catalytic graphitization methods over the past two decades are described.

“…7,8 Accelerator mass spectrometric-based techniques were employed in the early radioisotope studies allowing for the stable identification of tritium, 14 C, and 10 Be. 9 Accelerator-based techniques have been extensively reviewed, [10][11][12][13][14][15] and while they enjoy significant applicability, they generally fall outside the energy regime of soft landing. Once again the calutron and Manhattan Project roots of accelerator preparative techniques become apparent.…”

Preparative mass spectrometry has become a diverse field that covers the spectrum of kinetic energy deposition. Of these methods, soft-landing mass spectrometry has many fundamental properties, which make it an advantageous technique for ion isolation and deposition. Its definition implies the preservation of ionic structural integrity after landing, which ensures the structure-function relationship of a molecule remains intact. Here the focus is on the instruments and applications of studying ion-surface landing in the hyperthermal and thermal kinetic energy regimes. Soft-landing preparative mass spectrometry covers the breadth of mass spectrometric ionization sources, instrumental configurations, and molecular families. Due to the diverse nature of soft landing, and to maximize readability, this review has been organized according to instrumental considerations and molecular families, with a discussion of theoretical work at the end.
