SpletAs a surface-sensitive technique capable of identifying organic and inorganic materials, TOF-SIMS is a particularly useful tool to assist in determining root cause of failure mechanisms. Splet飞行时间-二次离子质谱仪（TOF-SIMS），是一种 非常灵敏的表面分析技术 。 它利用一次离子激发样品表面微量的二次离子，根据二次离子飞行到探测器的时间不同来测定离子质量。 由于TOF-SIMS中离子飞行时间只依赖于它们的质量，故其一次脉冲就可得到一个全谱，离子利用率很高，能实现对样品 几乎无损的静态分析 。 TOF-SIMS具有 检测极限极低 、 分 …

Spletpolydimethylsiloxane (PDMS), which has a very low surface tension and thus preferentially segregates on the surface of sample. The silicone contaminant on the surface will play a role of “mask” or “cover” so that ToF‐SIMS will detect the strong signal from silicone rather than the real sample. Splet01. jul. 2024 · Time-of-flight secondary ion mass spectrometry (ToF-SIMS) is one of the few in situ high spatial resolution techniques capable of identifying organic compounds and correlating their distribution with morphological features indicative of life (e.g., microfossils, stromatolitic biofabrics, biominerals) ( Cady et al., 2003, Oehler and Cady, 2014 ).
