Time-of-Flight Secondary Ion Mass Spectrometry [PDF]

Microscopy Today, 2011
The properties of many modern products are not only governed by their surface morphology and structure but also by their surface chemistry. For example, in some cases a contamination of less than a monolayer of molecules can be responsible for the failure of a coating with all its consequences (aesthetics, protection, life time, and so on).

COSIMA data analysis using multivariate techniques [PDF]

Geoscientific Instrumentation, Methods and Data Systems, 2015
We describe how to use multivariate analysis of complex TOF-SIMS (time-of-flight secondary ion mass spectrometry) spectra by introducing the method of random projections.

Enhancement of ion intensity in time-of-flight secondary-ionization mass spectrometry [PDF]

Journal of the American Society for Mass Spectrometry, 1996
Enhancement of ion intensity in static secondary-ionization mass spectrometry (SIMS) has been achieved by using a matrix-assisted sample preparation technique. Previous investigations of polymers and biomolecules by SIMS indicated that secondary-ion (SI) yield is dependent on substrate coverage.

Lipid mapping in human dystrophic muscle by cluster-time-of-flight secondary ion mass spectrometry imaging

Journal of Lipid Research, 2008
Human striated muscle samples, from male control and Duchenne muscular dystrophy-affected children, were subjected to cluster-time-of-flight secondary ion mass spectrometry (cluster-ToF-SIMS) imaging using a 25 keV Bi3+ liquid metal ion gun under static ...
