“…Increasing the distance between the sampling orifice and the cathode favoured detection of structural fragments analogous to those produced by 70 eV EIMS. Strikingly, sampling close to the cathode increased the relative importance of molecular ions produced by Penning ionization whereas sampling further from the cathode maximized detection of protonated molecules generated through proton transfer reactions with, for instance, ArH 1 .…”

“…the various aspects of analytical atomic spectrometry and follows the same format as last year's. 1 Although an attempt is made to consider all relevant refereed papers, conference abstracts, reports, book chapters and patents for inclusion in this review, the content of the review is highly selective. The selection of papers is based on criteria applied to focus sharply on the most significant developments in instrumentation and methodology or improved understanding of the fundamental phenomena involved in the MS process.…”

The conditions necessary for the complete decomposition of six organic arsenic compounds, namely methylarsonic acid (MMAA), dimethylarsinic acid (DMAA), trimethylarsine oxide, tetramethylarsonium iodide, arsenocholine bromide (AsC) and arsenobetaine (AB), were investigated. The degree of decomposition of the arsenic compounds was monitored using a hydride generation (HYD) technique, because the response from this system depends strongly on the chemical species of arsenic, with inorganic arsenic (the expected product from these decomposition experiments) giving a much more intense HYD signal than the organic arsenic compounds. The arsenic compounds were decomposed by heating them with three types of acid mixture, namely HNO 3 -HClO 4 , HNO 3 -HClO 4 -HF, or HNO 3 -HClO 4 -H 2 SO 4 . Both MMAA and DMAA were decomposed completely using any of the mixed acids at a decomposition temperature of 200 • C or higher. The HNO 3 -HClO 4 -H 2 SO 4 mixture was the most effective for decomposing AsC and AB, which are the most difficult compounds among all types of organic arsenic compound to decompose and render inorganic. The complete decomposition of AB was only achieved, however, when the temperature was 320 • C or higher, and the sample was evaporated to dryness. When the residue from this treatment was examined by high-performance liquid chromatography combined with inductively coupled plasma atomic emission spectrometry, all of the arsenic was found to be present as arsenic(V). The optimized conditions (HNO 3 -HClO 4 -H 2 SO 4 at 320 • C) for decomposing AB were then used to determine the total amount of arsenic in marine organisms known to contain AB.

“…For an authoritative account of the recent advances in ICP-MS, including magnetic sector instrumentation and laser ablation sample introduction, readers should consult the latest Atomic Spectrometry Update on atomic mass spectrometry. 323 In geochemistry, one of the major growth areas has been the applications of magnetic sector ICP-MS, and this is reflected in the Update. For clarity, the authors have decided to distinguish between developments in quadrupole-based ICP-MS and those in magnetic sector ICP-MS, although some aspects, such as isotope dilution, will be pertinent to both.…”
