Isotopic analysis of lead in sub-nanogram quantities by TIMS using a 202 Pb- 205 Pb spike

Amelin, YuriDavis, W.J.2015-12-080267-9477http://hdl.handle.net/1885/37057We present a method for isotopic analyses of Pb in sub-nanogram quantities by thermal ionization mass spectrometry with fractionation correction using a 202Pb-205Pb spike. The procedure is simple, fast, easy to automate, and requires only one analysis ofKeywords: Fractionation; Grain size and shape; Ionization; Isotopes; Mass spectrometry; Thermoanalysis; Double spike (DS); External normalization (EN); Isotopic ratios; Thermal ionization mass spectrometry (SIMS); LeadIsotopic analysis of lead in sub-nanogram quantities by TIMS using a 202 Pb- 205 Pb spike200610.1039/b606842a2015-12-08
