Atomic Spectrometry Update—Clinical and Biological Materials, Foods and Beverages
Literature Information
The references included in this the eighth ASU under the heading of Clinical and Biological Materials, Foods and Beverages, are from 92/C339 to 93/C909. As noted last year, there is now an increasing range of multi-element techniques being used and, while important, ICP-MS does not dominate as it once was suspected that it would. This year has seen a growth in the use of stable isotopes with measurements generally made by ICP-MS. However, a particular development has been with accelerator MS for the determination of 26Al. This has provided, for the first time, a tracer for Al metabolism experiments. A symposium on speciation in biological analysis provided the stimulus to much new work, particularly with As and Hg, and many of the papers from the meeting are included in this review. Several of these and other papers made use of Fl techniques, a develpment which was enhanced by a new commercial Fl system for AAS. Procedures for preconcentration, either separate from or linked to the Fl technique, featured in a number of reports. Aluminium no longer stands out as the single element of greatest interest. As already seen, there are many entries for As and Hg, but the main features are the increased number of Se papers and the larger overall number of elements which has been covered.

Journal of Analytical Atomic Spectrometry

The Journal of Analytical Atomic Spectrometry (JAAS) is the central journal for publishing innovative research on fundamentals, instrumentation, and methods in the determination, speciation and isotopic analysis of (trace) elements within all fields of application. This includes, but is not restricted to, the most recent progress, developments and achievements in all forms of atomic and elemental detection, isotope ratio determination, molecular analysis, plasma-based analysis and X-ray techniques. The journal welcomes full papers, communications, technical notes, critical and tutorial review articles, editorials, and comments, in addition to the Atomic Spectrometry Updates (ASU) literature reviews that are prepared by an expert panel. Submissions are welcome in the following areas, but note this list reflects the current scope and authors are strongly encouraged to contact the Editorial team if they believe that their work offers potentially new and emerging research relevant to the journal remit: Fundamental studies in the following. New and existing sources for atomic emission, absorption, fluorescence and mass spectrometry and those that provide both atomic and molecular information Sample introduction techniques for solids, liquids, gases Improvements in sensitivity, selectivity, precision, accuracy and/or robustness Isotope ratio measurements, including techniques for improving precision and mass bias correction Single channel and multichannel simultaneous detection systems Chemometrics, statistics, calibration techniques and internal standardisation Theoretical and numerical modelling of fundamental processes related to all of the above methodologies Novel or improved methodologies in areas of application including, but not limited to the following.
