SIMS analysis and the TOF-SIMS variant: high resolution and simultaneous detection
TOF-SIMS analysis
The TOF-SIMS analysis is particularly valued for its ability to provide detailed information on elemental chemical composition both at the surface and in the depth of materials (down to 1 nm).
It not only makes it possible to examine the surface to identify the elements and molecules present, but also to perform depth profiles by progressively removing layers, which reveals compositional variations at different levels. Thus, this technique stands out for its ability to identify the molecular structure of compounds.
SIMS analysis
Essential for surface studies, this dual analysis capability, spatial and molecular, makes TOF-SIMS analysis an essential tool for surface studies, the study of interactions between materials, understanding the presence of corrosion, analysis of coatings and many other applications.
TOF-SIMS analysis
TOF-SIMS analysis is a cutting-edge technique, offering high sensitivity and molecular resolution in the context of extreme surface analysis and the study of the chemical composition of materials.
TOF-SIMS analysis provides qualitative and semi-quantitative information on the elements and molecules present.
Moreover, it is a high-resolution imaging technique that makes it possible to map the distribution of elements and molecules on the surface of a sample with high spatial resolution.
This capability enables the FILAB laboratory to understand surface heterogeneities and material interfaces.
SIMS analysis and the TOF-SIMS variant: High resolution and simultaneous detection
Thanks to its excellent sensitivity (detection limit on the order of ppm), SIMS analysis (ToF-SIMS) is a cutting-edge technical solution for identifying molecular or elemental traces at the extreme surface. This method is an ideal initial screening tool: it secures the first diagnostic step before, if necessary, moving on to more specific complementary analysis such as XPS to further refine quantification.

FAQ
The TOF-SIMS extreme surface analysis first involves sample preparation, followed by introduction into the spectrometer’s vacuum chamber. A primary ion beam bombards the surface, releasing secondary ions that are then identified by their flight time, making it possible to determine the chemical composition of the surface.
Its principle consists of bombarding the surface to be analyzed with a pulsed source of primary ions (Ga+, Bin+, Au+, C60+, …) in order to produce secondary ions from the first monatomic layers of the sample. These secondary ions, whether positive or negative, are then focused and accelerated in a time-of-flight analyzer, where their transit times depend on their masses. By coupling this with a primary ion beam scanning device, a map of the different chemical elements and molecular species on the sample surface is obtained.
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.
In a 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. The molecules are simply desorbed or fragmented into several pieces. The secondary ions, made up of fragments of the original 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.
The SIMS analysis is a laboratory technique used to determine the composition of a material by bombarding its surface with ions. This bombardment releases particles from the material’s surface, which are then analyzed to identify the chemical elements and their quantities. This method is highly precise but destructive; in fact, it can detect very small amounts and may damage the sample.
The TOF-SIMS (Time-of-Flight Secondary Ion Mass Spectrometry) is an advanced form of SIMS analysis. It uses a time-of-flight analyzer, which measures the mass of secondary ions according to their travel time. This technique offers very high mass resolution, makes it possible to detect a large number of chemical species simultaneously, and is particularly well suited to qualitative analysis, mapping and depth profiling on complex materials (multilayer, organic, contamination, etc.).
The SIM mode (Selected Ion Monitoring) in mass spectrometry consists of tracking only a limited number of predefined ions, rather than analyzing the entire mass spectrum. This mode helps increase sensitivity and specificity for certain target compounds. It is particularly useful when you want to detect or quantify known substances, even at very low concentrations.
TOF-SIMS analysis makes it possible to identify traces of contamination, characterize thin films, or study the chemical homogeneity of critical surfaces. It is particularly useful in sectors where surface quality directly affects product performance: microelectronics, biomaterials, technical coatings, etc.
Even trace contamination can impair coating adhesion, cause premature corrosion, disrupt a chemical reaction, or generate manufacturing defects. TOF-SIMS analysis makes it possible to precisely locate and identify these contaminants.
Yes, TOF-SIMS is a key tool in nonconformity investigations. It makes it possible to analyze highly localized areas, such as cracks, bubbles, delaminations, or defective interfaces, in order to understand their chemical cause.
Absolutely. TOF-SIMS analysis enables depth profiling with nanometric resolution, ideal for characterizing the thickness, composition, and layering order in multilayer systems.
TOF-SIMS can analyze extremely small areas, down to a few square microns, making it an ideal method for localized studies or specific 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.
SIMS analysis brings together different secondary ion mass spectrometry techniques. TOF-SIMS (Time-of-Flight SIMS) uses a time-of-flight analyzer, which provides high mass resolution and simultaneous detection of all secondary ions, ideal for highly detailed qualitative and mapping analysis.
TOF-SIMS can be used at different stages:
– In R&D, to characterize new materials or validate a deposition process;
– In the production phase, to check surface conformity;
– In post-mortem, to analyze a failure or a quality defect.
