Molecular Imaging with High Spatial Resolution and High Mass Resolution (HR²) - TOF-SIMS

The new PHI nanoTOF is uniquely equipped to provide high spatial resolution molecular imaging with high mass resolution and sufficient ion beam current to obtain data quickly. Shown below are images of micro droplets of organic contamination on a surface. The images were extracted for a data file acquired in six minutes with a 25 µm field of view.

PHI TOF-SIMS images of micro-droplet contamination on a surface. The red image represents mass spectra from a low molecular weight hydrocarbon oil, the green image for aromatic hydrocarbons, and the blue image is represents the substrate.
