// Time-of-Flight Secondary Ion Mass Spectometry (ToF-SIMS)

The time-of-flight mass spectrometry of secondary ions is a materials characterization method which delivers laterally resolved depth profiles. Our TOF.SIMS 5 device made by IONTOF can be used to detect all elements of the periodic table.

  • Detection of trace elements up to a concentration of few ppm
  • Mass resolution of 12,000 which allows for a differentiation between O2 and S
  • 3D depth profiling in the micrometer range with a maximal lateral resolution of 200 nm (matrix elements)
  • Quantification of the depth profiles via reference samples
  • Detection of entire organic modules or their fractions, masses of up to 10,000 u
  • Measurement of non-conductive materials by way of charge compensation
  • Measurement of mobile ions with a chilled sample holder and soft sputtering sources
  • Handling of samples which are sensitive to air or water

  • Erfassen von Spurenelementen bis zu einer Konzentration von wenigen ppm
  • Massenauflösung von 12.000, was eine Unterscheidung von O2 zu S ermöglicht
  • 3D-Tiefenprofilierung im Mikrometerbereich mit einer maximalen lateralen Auflösung von 200 nm (Matrixelemente)
  • Quantifizierung der Tiefenprofile über Referenzproben
  • Detektion ganzer organischer Moleküle oder ihrer Fraktionen, Massen bis 10.000 u
  • Messung isolierender Materialien über Ladungskompensation
  • Messung mobiler Ionen durch gekühlten Probenhalter und sanfte Sputterquellen
  • Probenhandling von luft- oder wasserempfindlichen Proben
