WebbToF-SIMS at a glance. Time of Flight Secondary Ion Mass Spectrometry (ToF-SIMS) is a highly sensitive analytical technique that describes the chemical composition and distribution of a sample surface. It uses a range of incident ion sources to impact on solid surfaces and generate secondary ions that can be analysed by a time of flight (or ... WebbSIMSの測定モードには,一次イオンの照射量 の違いによってDynamic-SIMSとStatic-SIMSの二 種類があり,TOF-SIMSは後者の範疇に含まれる。 それぞれ二次イオンの発生メカニズムが異なるた め,得られる情報の質が両者で大きく異なってい る。 Dynamic-SIMSは,大量の一次イオンの照射に よって試料表面をスパッタすることにより,二 …

WebbTime-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.
