ToF-SIMS analysis in a laboratory
Your needs: characterize the extreme surface chemical composition of a sample using TOF-SIMS analysis
TOF SIMS, state-of-the-art technology
Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS), or sims analysis, is an imaging and analysis technique used to obtain elementary and molecular information on the species present at the extreme surface of solid-state samples.
TOF SIMS analysis
TOF SIMS analysis is a cutting-edge technique, offering sensitivity and high molecular resolution for extreme surface analysis and the study of the chemical compositions of materials.
TOF-SIMS analysis provides qualitative and semi-quantitative information on the elements and molecules present.
Furthermore, it is a high-resolution imaging technique that maps the distribution of elements and molecules on the surface of a sample with high spatial resolution. This capability allows the FILAB laboratory to understand surface heterogeneities and material interfaces.
In short, it provides information on the chemical composition, spatial distribution of elements, and chemical bonds of the sample.
Why perform a TOF SIMS analysis in the laboratory?
TOF SIMS analysis is particularly valued for its ability to provide detailed information on the chemical composition of materials, both at the surface and at depth (down to 1 nm).
It not only allows for surface examination to identify the elements and molecules present, but also allows for depth profiles to be created by progressively removing layers, revealing compositional variations at different levels. This technique is thus distinguished by its ability to identify the molecular structure of compounds.
Essential for surface studies, this dual analysis capacity, spatial and molecular, makes TOF SIMS analysis essential for surface studies, the study of interactions between materials, understanding the presence of corrosion, the analysis of coatings and many other applications.
The surface sensitivity of the sims analysis
ToF-SIMS is therefore a very highly sensitive surface analysis technique that achieves detection limits for elements or molecules in the ppm range.
The high sensitivity of TOF-SIMS makes it an excellent initial tool for identifying the types of species present in a sample. Once SIMS analysis is complete, other methods, such as XPS, can be used to obtain more detailed information. Moreover, SIMS analysis can detect species at much lower levels than traditional systems.
Materials and Surfaces concerned
This technique can be applied to a wide variety of materials, including polymers, metallic materials, ceramics, and composite materials, films, glass and fiberglass, dental implants, and more, without requiring complex sample preparation.
All conductive and insulating materials that are stable under ultra-high vacuum can be analyzed by ToF-SIMS: metals, alloys, semiconductors, polymers, varnishes, paints, adhesives, additives, surfactants, ceramics, glass, wood, paper, textiles, ultra-high vacuum, thin films, and more.

FAQ
Extreme surface analysis by TOF-SIMS involves first preparing the sample, then introducing it into the spectrometer's vacuum chamber. A beam of primary ions bombards the surface, releasing secondary ions which are then identified by their time-of-flight, enabling the chemical composition of the surface to be determined.
The principle consists in bombarding the surface to be analyzed with a pulsed source of primary ions (Ga+, Bin+, Au+, C60+, ...) to produce secondary ions from the first monoatomic layers of the sample. These secondary ions, whether positive or negative, are then focused and accelerated in a time-of-flight analyzer, where their travel time is a function of their mass. Coupled with a scanning device for the primary ion beam, this provides a map of the various chemical elements and molecular species on the sample surface.
TOF-SIMS can detect elements at extremely low concentrations, down to levels of a few parts per million (ppm), depending on the sample matrix and experimental conditions.
SIMS analysis is a laboratory technique for determining the composition of a material by bombarding its surface with ions. This bombardment releases particles from the surface of the material, which are then analyzed to identify the chemical elements and their quantities. This method is highly accurate, but destructive: it can detect very small quantities and can damage the sample.
In static SIMS analysis, a pulsed primary beam targets only the first monolayer of the sample.
Unlike dynamic SIMS analysis, this approach preserves the molecular integrity of the surface. Molecules are simply desorbed or fragmented into several pieces. Secondary ions, consisting of fragments of the initial molecules, are then detected by a time-of-flight spectrometer. Molecular ions weighing up to 10,000 amu can be identified, providing detailed information on the molecular structure of organic compounds.
TOF-SIMS analysis can identify traces of contamination, characterize thin layers, or study the chemical homogeneity of critical surfaces. It is particularly useful in sectors where surface quality directly influences product performance: microelectronics, biomaterials, technical coatings, etc.
Contamination, even at trace levels, can impair the adhesion of a coating, cause premature corrosion, disrupt a chemical reaction or generate manufacturing defects. TOF-SIMS analysis allows these contaminants to be precisely located and identified.
Yes, TOF-SIMS is a key tool in non-conformity investigations. It allows for the analysis of very localized areas, such as cracks, bubbles, delaminations, or defective interfaces, to understand the chemical cause.
Perfectly. TOF-SIMS analysis enables depth profiling with nanometer resolution, ideal for characterizing the thickness, composition and order of layers in multilayer systems.
TOF-SIMS is one of the most sensitive surface analysis techniques: it can detect concentrations at the ppm (parts per million) level, or even lower, in the first few nanometers of a material.
TOF-SIMS can analyze extremely small areas, down to a few square microns, making it an ideal method for localized studies or on precise defects.
Yes. Unlike other techniques, static TOF-SIMS preserves organic molecular fragments, making it possible to identify polymers, lubricants, additives, biological residues, or other organic compounds.
