We present a new technique for the precise determination of platinum (Pt) stable isotope ratios by multiple-collector inductively coupled plasma mass spectrometry (MC-ICPMS) using two different Pt double-spikes (Pt–Pt and Pt–Pt). Results are expressed relative to the IRMM-010 Pt isotope standard as the parts per million difference in Pt/PtPt ratios (mPt). Repeated measurements of the IRMM-010 Pt standard in two different laboratories, consuming ca. 40–85 ng of Pt, show that a long-term external… CONTINUE READING
