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...

ICP-MS methods Chlorine, bromine, and iodine were measured by Tagami et al. [50] in aqueous samples using inductively coupled plasma-mass spectrometry (ICP-MS). Since iodine has only one stable isotope, m/z = 127 was scanned for iodine determination. For chloride and bromide determination m/z of 35 and 79 were, respectively, applied. Cesium (m/z = 133) was used as an internal standard during ICP-MS determination to monitor the change in counting efficiency.
