Goal: The present study on a Thermo Scientific™ Triton Plus™ assesses the accuracy of 500 ng Nd+ load analyses on La Jolla Nd reference standard.

Goal: The present study on a Thermo Scientific™ TRITON Plus™ TIMS assesses the precision and reproducibility over 1 year of Nd isotope analyses in metal form (Nd+) on double filament assemblies on one Nd standard for sample loads ranging from 500 ng to 100 ng, using 1011 ohm amplifiers, automated mode and analytical runs of about 1 hour.

Goal: This application note demonstrates that high precision 176Hf/177Hf isotope ratios can now be obtained from 25 μm diameter laser ablation spots.

Goal: The present study on a Thermo Scientific TRITON Plus instrument is intended to assess precision and accuracy of Cr isotopic analyses in static mode using the virtual amplifier, 1011 ohm current amplifiers, automated mode and >3 time shorter analyses compared to literature.

Goal: Ca isotope analysis was achieved through high-precision mass spectrometry by TIMS and complete chromatographic separation of Ca from elements susceptible to induce isobaric interferences during mass spectrometry analysis (Mg, K, Sr).

Goal: This application note describes the analytical performance of the Thermo Scientific™ NEPTUNE™ Plus multicollector ICP-MS (MC-ICP-MS) for measuring uranium isotopes from 2 ng uranium samples

Goal: This application note describes the analytical performance of the Thermo Scientific™ NEPTUNE Plus™ for measuring uranium isotopes from low enriched uranium in NBS U-045, U-030 and U-010. The methodology follows a standard test protocol that is used within nuclear industry.

Goal: In this study we evaluate the performance of an improved Multi Ion Counting (MIC) setup for Os isotope ratio measurements using an array of new Compact Discrete Dynode (CDD) multipliers installed into the Thermo Scientific TRITON TIMS

Goal: This application note reports the sensitivity enhancements Among the new features are an improved pumping capacity option at the interface and a new sample cone

Goal: In order to overcome the limitations of sequential sampling of U-Th-Pb and Hf isotopes from different sites in zircons, a fast scanning single collector and a multicollector inductive coupled plasma mass spectrometer have been coupled in parallel to a New Wave UP213 213 nm UV laser ablation system.

Goal: The purpose of this study is to explore the achievable external reproducibility of the elements Sr, Nd and Hf on the NEPTUNE under different experimental conditions.

Goal: In this study, we aim to narrow the gap between ion counting and Faraday cup measurements by using a new set of current amplifiers with Tera-Ohm feedback resistors (1012 Ω), instead of the standard 1011 Ω eedback resistors.

Goal: We describe and compare the results from three strategies for performing interference corrections, using Nd-Sm data measured on the Thermo Scientific NEPTUNE MC-ICP-MS

Goal: This note descrbes the method to analyse BO2- ions by negative ion thermal ionization mass spectrometry on the Triton.
