New Olivine Reference Materials for Secondary Ion Mass Spectrometry Oxygen Isotope Measurements

open access: yesCrystals, 2023
To accurately analyze the oxygen isotope of olivine using secondary ion mass spectrometry (SIMS), appropriate standard materials are required to calibrate for matrix effects caused by chemical composition differences between the samples and the standard ...

Expanding the Efficacy of Fingermark Enhancement Using ToF-SIMS

open access: yesMolecules, 2023
Time-of-flight secondary ion mass spectrometry (ToF-SIMS) has been shown to enhance fingermark recovery compared to standard processes used by police forces, but there is no data to show how generally applicable the improvement is. Additionally, ToF-SIMS
