Secondary ion mass spectrometry, SIMS, is a method of choice for the characterization of nanoparticles, NPs. For NPs with large surface-to-volume ratios, heterogeneity is a concern. Assays should thus be on individual nano-objects rather than an ensemble of NPs; however, this may be difficult or impossible. This limitation can be …

WebbThe abbreviation TOF-SIMS is an acronym for the combination of secondary ion mass spectrometry (SIMS) with a time-of-flight (TOF) mass analyser. The sample to be analysed is bombarded with a primary ion beam with a kinetic energy of a few keV. The ions collide with the surface, releasing their energy and generating a shock cascade.
