TOF-SIMS is used infrequently in PVC studies; in the majority of cases, to determine surface morphology of polymers or polymer blends. 259–263 TOF-SIMS helped to establish reasons for low …
Webb18 maj 2024 · Time-of-Flight Secondary Ion Mass Spectrometry (ToF SIMS) is a surface analysis technique used to study the chemical composition of solid surfaces and thin films in three dimensions. A focused beam of primary ions bombards a target surface, creating a plume of neutral atoms/molecules, secondary ions, and electrons. WebbThe 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.
WebbTime-of-flight secondary ion mass spectrometry (TOF-SIMS) is a key analytical technique for detecting, identifying, and imaging the distribution of both elements and molecules on the surface of materials. TOF-SIMS is the only mass spectrometry imaging technique that provides less than 70 nm spatial resolution with full mass range detection. The PHI
