WebbSIMS, secondary ion mass spectroscopy, is a surface chemical analysis technique for solid materials. As its name indicates, a specimen is bombarded with a primary ion beam and the secondary ions are collected using a detector – a spectrometer. The secondary ions provide information on the elemental, molecular, and isotopic composition of a ... Webb16 maj 2024 · What is Secondary Ion Mass Spectrometer (SIMS) As a class, SIMS instruments (aka ion microprobes) use an internally generated beam of either positive (e.g., Cs) or negative (e.g., O) ions (primary …
