WebbThis is in contrast to dedicated SIMS instruments, which perform SIMS excellently, but can’t do much else. Spatial resolution. The spatial resolution achievable in a FIB-SIMS image depends on the spot size of the primary ion (FIB) beam, the energy of the beam, the nature of the sample, as well as the secondary ion yield. WebbTOF-SIMS and MALDI-TOF are two complementary techniques, whereas TOF-SIMS offers higher spatial resolution and MALDI-TOF extracts larger volumes implying higher ion yields allowing the detection of large molecules such as proteins (Fletcher et al., Reference Fletcher, Lockyer and Vickerman 2011).Both techniques give information to identify and …

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 ...
