Inductively coupled plasma mass spectrometry in geoanalysis

摘要: Abstract Inductively coupled plasma mass spectrometry (ICP-MS) has had a profound effect in the discipline of geoanalysis since its commercial availability 1983. In particular, ability to determine precious metals, rare earth elements (REEs) and refractory such as Hf, Ta W at their natural levels geological materials dramatically improved through application this highly sensitive, multielement technique. Its capability measure individual isotopes been directed mainly towards Re-Os chronometer pair ore genesis studies, lesser extent quantitation Pb isotope ratios. The impact ICP-MS date exploration geochemistry is reviewed paper, together with description instrumentation, principles technique procedures suitable for optimal use. As every analytical technique, suffers from interferences; although degree spectral interference lower than ICP atomic emission (ICP-AES), opposite true case matrix-induced effects. intolerance solutions containing high concentrations dissolved solids (>0.2%) fostered research into modes sample introduction other conventional nebulisation. Applications alternate means based upon electrothermal vaporisation, laser ablation, slurry nebulisation flow injection are discussed here. Waters an ideal medium analysis by ICP-MS, though there yet only few studies examining potential use type geochemistry. happened 1980s complementary ICP-AES, 1990s will see establishment rugged, efficient tool production-oriented laboratories continuing design improvements new applications.
