Dynamic sims vs tof-sims

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. WebA SIMS (secondary ion mass spectrometry) detector enables sensitive surface analysis for many industrial and research applications. The technique provides detailed elemental and isotopic information about the sample and is capable of depth profiling analysis.
