WebbFör 1 dag sedan · ToF SIMS is carried out in static mode, that is to say, the primary ion beam is maintained at a very low fluence typically less than 10 12-15 ions/cm 2 (sample dependent). This very low fluence ensures that secondary ions are not emitted from an area damaged previously by another primary ion, resulting in the emission of elemental …

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).
