Potassium Stable Isotopic Compositions Measured by High-Resolution MC-ICP-MS [PDF]
, 2012 Potassium isotopic (K-41/K-39) compositions are notoriously difficult to measure. TIMS measurements are hindered by variable fractionation patterns throughout individual runs and too few isotopes to apply an internal spike method for instrumental mass ...

In situ Sr isotope measurement of small glass samples using multiple-Faraday collector inductively coupled plasma mass spectrometry with 10^12Ω resistor high gain Faraday amplifiers [PDF]
, 2014 An analytical protocol was developed for correcting Kr baseline-induced bias and Rb isobaric overlap factors to analyse Sr isotope ratios for small glass samples using excimer laser ablation (LA) with an Aridus II desolvating nebuliser dual-intake system

Quantification of 60Fe atoms by MC-ICP-MS for the redetermination of the half-life [PDF]
, 2018 In many scientific fields, the half-life of radionuclides plays an important role. The accurate knowledge of this parameter has direct impact on, e.g., age determination of archeological artifacts and of the elemental synthesis in the universe.
