http://www.nuance.northwestern.edu/docs/keckii-pdf/what-is-tof-sims.pdf WebThe early‐stage spectrometer is operated in a mode of dynamic SIMS (DSIMS). The DSIMS directs a high flux of primary ion to the sample surface, eroding the surface rapidly. Therefore, DSISM is not suitable for ultra‐thin surface analysis. A static SIMS (SSIMS) was developed in 1970’s. WebTime-of-flight secondary-ion mass spectrometry (TOF-SIMS) provides sub-micrometer elemental, chemical, and molecular characterization and imaging of solid surfaces. Different from D-SIMS ("dynamic" SIMS), this technique enables analyzing the outermost one or two mono-layers of a sample while basically preserving molecular information.

"WebSIMS must be applied in the dynamic regime for quantitative compositional analysis of surfaces, but static mode SIMS is required for other applications, notably identification of organic species. It is an advantage of TOF-SIMS that it can be employed in either mode. A historical overview of TOF-SIMS developments is given by Benninghoven (2001). " - Dynamic sims vs tof-sims

Dynamic sims vs tof-sims

WebTime-of-Flight Secondary Ion Mass Spectrometry (TOF-SIMS) provides elemental, chemical state, and molecular information from surfaces of solid materials. The average depth of analysis for a TOF-SIMS measurement is approximately 1 nm. Physical Electronics TOF-SIMS instruments provide an ultimate spatial resolution of less than 0.1 µm. WebTime of Flight (ToF) Mass Spectrometry. Is an incredibly powerful technique that allows for sub-integer m / z detection of atomic species. A good example of this is that ToF can distinguish between A 28 A 2 2 28 Si ( m = 27.976 A u) and N A 2 ( m = 28.006 A u ). This is beyond the resolution of many other detectors.
