Analysis of COSIMA spectra: Bayesian approach [PDF]
Geoscientific Instrumentation, Methods and Data Systems, 2015 We describe the use of Bayesian analysis methods applied to time-of-flight secondary ion mass spectrometer (TOF-SIMS) spectra. The method is applied to the COmetary Secondary Ion Mass Analyzer (COSIMA) TOF-SIMS mass spectra where the analysis can be ...

Resolving sub-micrometer-scale zonation of trace elements in quartz using TOF-SIMS
, 2022 Quartz is abundant in the Earth's continental crust and persistent throughout the geological record. Trace element signatures in silica minerals can be used to infer processes operating in magmatic and hydrothermal systems. Conventional analyses of trace

Characterisation of protein nanotubes by ToF‐SIMS imaging
Surface and Interface Analysis, 2012 A growing number of nano‐objects such as nanotubes, capsules or beads are being developed for various biological and medical applications. In particular, the use of polymer templates for the synthesis of nanomaterials, using layer‐by‐layer assembly, has become a method of choice due to its simplicity and versatility in shapes and dimensions.

Probing Surface Information of Alloy by Time of Flight-Secondary Ion Mass Spectrometer
Crystals, 2021 In recent years, time of flight-secondary ion mass spectrometer (ToF-SIMS) has been widely employed to acquire surface information of materials. Here, we investigated the alloy surface by combining the mass spectra and 2D mapping images of ToF-SIMS.
