Time-of-Flight Secondary Ion Mass Spectrometry (TOF-SIMS) is a highly surface-sensitive analytical technique used to obtain elemental, isotopic, and molecular information from the surface of solid materials and compacted powders. This TOF-SIMS instrument features a Primary Ion Beam operating at 30 keV with a three-lens BiMn cluster nanoprobe. For sputtering sources (Secondary Ion Beams) the TOF.5 can utilize either a Thermal ionization Cesium source, an Oxygen electron impact gas ion source, or a fully integrated gas cluster ion source. The Bi Nanoprobe source provides high analysis currents of up to 20 pA for trace detection spectrometry and high-end depth profiling.
Each point of impact on the sample from the primary ion beam contains the entire mass spectrum as well as the X, Y and Z coordinates of that point of impact. With this information, we can create detailed ion images of the distribution of any species of interest on our sample, both in 2D and in 3D (in depth profile mode).
