Simultaneous in situ determination of U‐Pb and Sm‐Nd isotopes in monazite by laser ablation ICP‐MS
Geochemistry, Geophysics, Geosystems, 2014 Results are presented for in situ simultaneous determination of U‐Pb and Sm‐Nd isotopes in monazite using the Laser Ablation Split‐Stream (LASS) method. This method uses a laser ablation system coupled to a magnetic‐sector inductively coupled plasma mass

A search for ^(70)Zn anomalies in meteorites [PDF]
, 2009 No ^(70)Zn isotopic anomalies have been detected in primitive meteorites to a level of precision of less than 40 parts per million (2σ). Any pre-existing nucleosynthetic anomaly on ^(70)Zn was averaged out by mixing in the solar nebula before planetary

Alternative data reduction for precise and accurate isotope ratio determination via LA-MC-ICP-MS [PDF]
, 2008 An alternative approach for the evaluation of isotope ratio data using LA-MC-ICP-MS will be presented. In contrast to previously applied methods it is based on the simultaneous responses of all analyte isotopes of interest and the relevant interferences

Improving Precision and Signal/Noise Ratios for MC-ICP-MS
Procedia Earth and Planetary Science, 2015 AbstractHigh precision measurements of isotope ratios are improved by continuous innovations in multi-collector isotope ratio mass spectrometers. Recently, the Thermo Scientific TRITON Plus TIMS and NEPTUNE Plus MC-ICP-MS benefitted from the implementation of Faraday cup current amplifiers with 1013 ohm feedback resistors.
