WebbToF-SIMS is an imaging mass spectrometry (MS) technique that allows us to obtain isotopic, elemental, and molecular information from the surface of solid samples. A … WebbLe ToF-SIMS est en conséquence une méthode d’ionisation douce qui permet l’analyse moléculaire de surface. Les ions secondaires formés sont alors focalisés et accélérés avec une même énergie cinétique dans l’analyseur à temps de vol qui les sépare en fonction de leur rapport m/z avec une très bonne résolution en masse (ΔM/M > 10 000 à la masse 28).
