Inductively elements accessible

Whatever the analytical method and the determinand may be, the greatest care should be devoted to the proper selection and use of internal standards, careful preparation of blanks and adequate calibration to avoid serious mistakes. Today the Antarctic investigator has access to a multitude of analytical techniques, the scope, detection power and robustness of which were simply unthinkable only two decades ago. For chemical elements they encompass Atomic Absorption Spectrometry (AAS) [with Flame (F) and Electrothermal Atomization (ETA) and Hydride or Cold Vapor (HG or CV) generation]. Atomic Emission Spectrometry (AES) [with Inductively Coupled Plasma (ICP), Spark (S), Flame (F) and Glow Discharge/Hollow Cathode (HC/GD) emission sources], Atomic Fluorescence Spectrometry (AFS) [with HC/GD, Electrodeless Discharge (ED) and Laser Excitation (LE) sources and with the possibility of resorting to the important Isotope... 

Inductively coupled plasma mass spectrometry (ICP-MS), a relatively novel technique with high sensitivities for most elements, presents major attributes not available with other methods of isotopic analysis simple requirements for chemical processing, high sample throughput, acceptable level of measurement precision and bias, multi-element capability and reasonable accessibility and capital cost. The relatively low sensitivity for selenium, however, precludes the direct measurements in clinical matrices without analyte preconcentration (Hieftje and Vickers. 1989). The present state of development of ICP-MS for application to clinical matrices indicates that the technique can provide selenium isotope ratio measurements with the required accuracy and precision (Ting and Janghorbani, 1987 Ting et al., 1989).
