WebToF-SIMS is an ultra-high vacuum-based technique for measuring the chemical nature of atoms at and near the surface of materials. The sensitivity of the measurement is often better than parts per million, and the spatial resolution can be within the nano-scale. Instrument Specficiation Primary ion beam 25keV Bi (Bi+, Bi3+, Bi3++) Web15 mei 2013 · Time-of-flight secondary ion mass spectrometry (TOF-SIMS) and X-ray photoelectron spectroscopy (XPS) are well established surface techniques that provide both elemental and organic information from several monolayers of a sample surface, while also allowing depth profiling or image mapping to be carried out.
