ANALYSIS OF PLATINUM GROUP ELEMENTS AND GOLD IN GEOLOGICAL MATERIALS USING NIS FIRE ASSAY AND TE COPRECIPITATION; THE NIS DISSOLUTION STEP REVISITED

Gros M.; Lorand J.P.; Luguet A. (2002)

The NiS fire assay-Te coprecipitation separation procedure for inductively coupled plasma mass spectrometry (ICP-MS) analyses of platinum-group elements (PGE) in silicate rocks has been revisited with the aim of reducing ...
QUANTITATIVE DETERMINATION OF GOLD AND THE PLATINUM-GROUP ELEMENTS IN GEOLOGICAL SAMPLES USING IMPROVED NIS FIRE-ASSAY AND TELLURIUM COPRECIPITATION WITH INDUCTIVELY COUPLED PLASMA-MASS SPECTROMETRY (ICP-MS)

Oguri K.; Shimoda G.; Tatsumi Y. (1999)

New fire-assay and tellurium coprecipitation methods were developed for precise determination of Ru, Rh, Pd, Ir, Pt, and Au in geological samples by using ICP-MS. High recovery (>97%) of those elements was obtained by ...
