要旨

Based on the static high sensitivity inductively coupled plasma (SHIP) introduced by Buscher et al. (W. Buscher, A. Klostermeier, C. Engelhard, S. Evers, M. Sperling, J. Anal. At. Spectrom., 2005, 20, 308-314), a new torch design for ICP mass spectrometry was developed. The SHIP-torch, including the external air cooling system, was modified in order to allow its application as an ion source in a conventional ICP mass spectrometer. While the torch geometry was adjusted for its use in connection with the sampling interface, the principal shape of the torch remained the same as in the recently developed SHIP-OES-system. The plasma discharge was operated at 0.65 kW rf power with a total plasma gas flow rate of 1.95 L min−1 and the mass spectrum was investigated. A standard pneumatic nebuliser was used as sample introduction system and the ion signals of a multi elemental standard solution were measured for different sample carrier gas flow rates from 0.2 to 1.4 L min−1. Limits of detection were obtained for a number of elements. These results were compared to those achieved with the conventional ICP-MS setting.

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. Biosciences, including elemental, speciation and isotopic analysis in biological systems, immunoassays based on metal-labeled antibodies, bio-imaging, and nanoparticle toxicology Geochemistry Environmental science Materials science, including engineered nanoparticles and quantum dots Metrology, including reference materials Forensic analysis Food and agricultural sciences Energy Archaeometry Molecular analysis. Molecular sources for elemental and isotopic analysis Atomic sources for molecular analysis Atomic and molecular techniques simultaneously used for complementary chemical information All contributions are judged on originality and quality of scientific content, and appropriateness of length to content of new science.
