Abstract
Concentrations of trace elements in an ice core obtained in the polar region have been determined by inductively coupled plasma mass spectrometry (ICP-MS) . For trace metals in the ice core, sample uptake and high sensitivity for analysis are also important due to the limited volume of sample and the low concentrations of analytes. A desolvated micro-concentric nebulizer (MCN-6000), which is a recent development and offers high nebulizer efficiency at low sample consumption volume, in combination with ICP-MS, permitted multi-element determination of ppt levels of Al, V, Cr, Fe, Cu, Zn, As, Ag, Cd, Pb and U within a 2ml sample from a ice core obtained from the Vestfonna ice cap (89° 58' N, 21° 02' E) in Nordaustlandet, Svalbard. The contamination on the ice core exterior was removed with a stepwise melting process. The concentrations of Al, Fe, Cu, Zn and Pb were determined from the results of this analysis.
