PHI nanoTOF II
Parallel Imaging MS/MS for Surface Aalysis
With parallel imaging MS/MS, TOF-SIMS peaks can now be identified unambiguously. The PHI nanoTOF II is a TOF-SIMS (Time-of-Flight Secondary Ion Mass Spectrometry) instrument for elemental, chemical and molecular imaging, with applications in many fields, including material development and failure analysis. TOF-SIMS uniquely combines sensitivity, spatial resolution and molecular specificity. For more information about how TOF-SIMS works, read our article.
- Detect and identify molecules from exact mass and characteristic fragments
- Parallel detection of all elements from Hydrogen to Uranium
- Elemental and molecular imaging with spatial resolution down to 70 nm
- Parts-per-million level elemental sensitivity
- Depth profiling and 3D imaging of elements and molecules
The patented TRIFT mass spectrometer from Physical Electronics delivers excellent sensitivity and can image highly topographic surfaces. Depending on your requirements, the PHI nanoTOF TOF-SIMS can be configured with a variety of options to optimise performance for organic materials, inorganic materials, or both.

Triple Focussing Time-of-Flight (TRIFT) Mass Analyser
The nanoTOF II is based on PHI’s patented TRIFT mass spectrometer, with three 90° sector electrostatic analysers (ESA).
This design eliminates metastable ions, to produce spectra with very low background and excellent detection limits. The TRIFT analyser has a larger angular acceptance, larger energy bandpass and a larger depth-of-field than any other analyser design.
HR2 Molecular Imaging
The new PHI liquid metal ion gun can achieve ion beam diameters of less than 500 nm in high mass resolution mode,
with higher beam currents than ever before. Achieve both high spatial resolution or high mass resolution in a single, fast analysis. The new mode is called HR2 imaging.
Cluster Source Ion Guns
Physical Electronics was the first surface analysis manufacturer to offer C60+ and Ar gas cluster ion beam sputtering. The 20 kV C60 ion gun can depth profile most organic and inorganic materials, with high sensitivity for organic spectroscopy. The versatile 20 kV Ar2500+ gas cluster ion beam is ideal for depth profiling organic films.
3D Chemical Imaging
3D FIB-TOF tomography characterises and images complex matrix chemistries that would not be possible with traditional sputter depth profile analysis. Accurate 3D images are acquired, along with high quality mass spectra throughout the analysis volume. (See example at top of page).
