TOF-SIMS in Cosmochemistry [PDF]

open access: yes, 2004
Time-of-flight secondary ion mass spectrometry (TOF-SIMS) was introduced into cosmochemistry about a decade ago. Major advantages of TOF-SIMS compared to other ion microprobe techniques are (a) parallel detection of all secondary ions with one polarity in a single measurement – both polarities in subsequent analyses, (b) high lateral resolution, (c ...

Spectroscopy in the analysis of bacterial and eukaryotic cell footprints on implant surfaces [PDF]

open access: yesEuropean Cells & Materials, 2012
We tested the suitability of two spectroscopic methods, x-ray photoelectron spectroscopy (XPS) and time of flight secondary ion mass spectrometry (ToF-SIMS), in the recognition of bacterial and eukaryotic cell footprints on implant surfaces.

TOF-SIMS (Michellod et al. 2023) [PDF]

open access: yes, 2023
PFA-fixed Olavius algarvensis specimens were embedded in paraffin and cut into 4 µm thick sections. The sections were de-waxed, wrap in aluminium foil and stored in a dessicator until TOF-SIMS analysis.

TOF-SIMS: Accurate mass scale calibration [PDF]

open access: yesJournal of the American Society for Mass Spectrometry, 2006
A study is presented of the factors affecting the calibration of the mass scale in time-of-flight secondary ion mass spectrometry (TOF-SIMS). At the present time, TOF-SIMS analysts using local calibration procedures achieve a rather poor relative mass accuracy of only 150 ppm for large molecules (647 u) whereas for smaller fragments of
