WebbSIMS (Secondary Ion Mass Spectrometry) and TOF-SIMS (Time of Flight-SIMS) are the same in terms of mass analysis of secondary ions emitted by primary ion beam bombardment. They differ greatly in primary ion beam type, equipment, and information obtained. Therefore, it is a method with completely different uses as follows. Webb13 sep. 2024 · ToF-SIMS (time of flight secondary ion mass spectroscopy) is a powerful surface analytical technique with superior chemical sensitivity, making it helpful in …

TOF-SIMS is a technique that can observe elemental, inorganic and molecular species present on the outermost surface of a sample, using a very small primary ion beam dose (~1e12 ions/cm 2 or less). It is also quite commonly known as static SIMS because it does not typically induce damage to the sample under ...
