Investigation of planktonic foraminifera with ToF‐SIMS [PDF]
Surface and Interface Analysis, 2002 Abstract Various oceanic sediment properties deliver useful information for reconstructing environmental parameters of the past. Those properties that are closely related to environmental parameters are called ‘proxies’. They are measurable descriptors for desired (but unobservable) variables.

Methods for evaluation of early bone healing at titanium implants [PDF]
, 2007 Titanium has for a long time been the implant material of choice when in need for abilities as strength, biocompatibility and stability. Although numbers of studies have been made, little is known about the early events in implant healing.

Multivariate analysis of 3D ToF-SIMS images: method validation and application to cultured neuronal networks [PDF]
, 2015 Advanced data analysis tools are crucial for the application of ToF-SIMS analysis to biological samples. Here, we demonstrate that by using a training set approach principal components analysis (PCA) can be performed on large 3D ToF-SIMS images of ...

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 ...

SIMS Studies of Allende Projectiles Fired into Stardust-type Aluminum Foils at 6 km/s [PDF]
, 2006 We have explored the feasibility of C-, N-, and O-isotopic measurements by NanoSIMS and of elemental abundance determinations by TOF-SIMS on residues of Allende projectiles that impacted Stardust-type aluminum foils in the laboratory at 6 km/s.
