Atomic spectrometry update - atomic mass spectrometry.
The MS and XRF updates have been published together since their introduction in 1988. In the last few years, however, the two sections have been prepared independently of each other and it therefore seemed appropriate to publish the two sections separately. With effect from this issue, the MS Update will appear in the October issue of JAAS and the XRF Update in the November issue. The format used for the MS section is broadly similar to that used last year, with some additional sub-headings. This Update is intended to cover all atomic and stable isotopic MS techniques, but not those used in studies of fundamental nuclear physics and exotic nuclei far from stability. Also excluded are those reports in which MS is used as a tool in the study of molecular processes and of gaseous components. the review is based on critical selection of developments in instrumentation and methodology, notable for their innovation, originality or achievement of significant advances, and is not intended to be comprehensive in its coverage. Conference papers are only included if they contain enough information to show they meet these criteria, and our policy in general remains one of waiting for a development to appear in a full paper before inclusion in the review. a similar policy applies to foreign language papers unlikely to reach a wide audience. Routine applications of atomic MS are not included in this Update and the reader is referred to the Updates on Industrial Analysis: Metals, Chemicals and Advanced Materials (96/416), Environmental Analysis (96/1444) and Clinical and Biological Materials, Food and Beverages (96/2479). Also excluded are those applications, even if not routine, which use atomic spectroscopy as a tool for the study of a non-atomic property, for example, the use of stable isotope labeling of carbon or nitrogen in biomolecules in metabolic studies. There have been few general reviews on atomic MS of note in the period covered by this update. That of Colodner et al.(95/3890) gave a general review of ion sources, in particular GDMS, ICP-MS, SIMS and TIMS, and that of Blades (95/2568 and 95/3077) was a very general overview of some of the techniques covered in this Update. The review of the literature in the period covered by this Update reveals strong advances in all areas, with a continuing push to achieve better analyses on smaller samples and in less time. Most advances generally require more sophisticated instrumentation, improved sample preparation methods or new methods of sample introduction. This is typified by advances in ICP-MS, which see considerable emphasis on sample introduction techniques and a move towards magnetic sector instruments. Most applications of ICP-MS are now highly routine. There is still, however, a desire to achieve affordable analysis with simplified and cost-effective instruments, as illustrated by the development of mobile, in-situ isotope MS for environmental studies.
