Trace element determinations in Fe–Mn oxides by high resolution ICP-MS after Tm addition

In order to propose an optimal analytical procedure specific ferromanganese (Fe–Mn) oxides, we investigated different modes of data acquisition using inductively coupled plasma mass spectrometry (ICP-MS). The results trace element and Rare Earth Element (REE) determination in eight Fe–Mn nodules crusts (FeMn-1, GSMC-1, GSMC-2, GSMC-3, GSPN-2, GSPN-3, NOD-A-1 NOD-P-1) are presented here. involves chemical dissolution the oxides addition a thulium (Tm) spike. correction measured values from potential isobaric interferences was both corrections based on mono-elemental solutions, high-resolution mode. obtained show that mode is unnecessary achieve high quality for REE oxides. Using our revised method, provide consistent set precise accurate widely used but poorly characterized certified reference materials.
