摘要:Abstract(#br)The analysis of environmental swipe samples for ultra-trace uranium (U) and plutonium (Pu) determinations is essential in the nuclear safeguards community. While mass spectrometry techniques for U and Pu detection continually improve, established separation meth...

摘要:... Results were compared with those derived from MC-ICP-MS, applied on the same samples, and analytical and practical aspects of the two techniques were compared.(#br)Both techniques showed an increased absorption and incorporation in red blood cells of the 58 Fe isotope in iron...

摘要:... Many comparative measurements for the isotopic composition of tungsten have been performed using either thermal ionization mass spectrometry (TIMS) or multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS). Yet, calibrated measurements of tungsten isotope ra...

摘要:Abstract(#br)We present new high precision Os isotope data obtained by solution-mode MC-ICP-MS for 4 different Os isotope reference materials and compare the data to that obtained by the N-TIMS method. Mass fractionation effects for MC-ICP-MS are evaluated and we demonstrate e...

摘要:... Previous studies have observed differences in absolute δ 11 B values of marine carbonates measured via negative thermal ionization mass spectrometry (N-TIMS) and multicollector inductively coupled mass spectrometry (MC-ICP-MS) that are relatively large compared to magni...

摘要:Abstract(#br)The sensitivity of multi-collector inductively coupled plasma mass spectrometers (MC-ICP-MS) can be significantly improved using different sample and skimmer cones with different orifice diameters and angles. In this study, an MC-ICP-MS with three typical combinatio...

摘要:Abstract(#br)A Pb isotope analytical method using a 207 Pb– 204 Pb double spike (DS) and a double-focusing MC-ICP-MS routinely yields standard and sample data with an external reproducibility <100 ppm for all Pb isotope ratios. With modest increases in analysis times (<10 min...

摘要:Abstract(#br)Multiple-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) has become the preferred method for precise and accurate measurements of the relative abundances of many radiogenic and stable isotopes in natural materials. Isotopic analyses by MC-ICP-MS...

摘要:Abstract(#br)We have optimized techniques to measure uranium and thorium isotopic compositions using secondary electron multiplier (SEM) and peak-jumping protocols on a multi-collector inductively coupled plasma mass spectrometer (MC-ICP-MS, Thermo Scientific Neptune Plus). ...
