An Introduction to FIB-SIMS Using the fibTOF - TOFWERK

WebbIn conventional TOF-SIMS instruments the mass resolution depends on the pulse width of the primary ion source and hence the resulting acquisition time and image resolution. The delayed extraction mode of the M6 overcomes this restriction and combines maximum image resolution with high spectrometry performance in a unique way. Webb20 feb. 2024 · TOF-SIMS data were converted to a matrix (n × m, where n = the number of pixels and m = the number of autosearched peaks) and loaded with matlab (Mathworks, MA). The same area in both the TOF-SIMS image and the microscopy image was chosen based on the patterns in image data. WebbStandard Ion Gun featuring FIB Function. The PHI nanoTOF 3 adds a FIB cross-sectioning function to the liquid metal ion gun. This allows small area cross-sectioning and TOF-SIMS analysis to be performed with a single ion gun. The entire process of cross-sectioning to analysis can be performed quickly and easily by computer operation. characteristics of a vein
