Web29 mrt. 2016 · ToF-SIMS spectra were obtained with a ToF-SIMS V (ION-TOF GmbH, Germany) equipped with a 25 keV Bi 3+ ion gun. For the ToF-SIMS spectrum, the ion gun was operated at 8.3 kHz with an average current of 0.28 pA (Bi 3+) at the sample holder. A bunch pulse of 0.7 ns duration resulted in mass resolution (M/ M) > 8000 at m/z 760. Web25 okt. 2011 · The use of polyatomic ion sources in time-of-flight secondary ion mass spectrometry (TOF-SIMS) has recently been developed, promising the enhancement of molecular ion yields and therefore an increase in instrument sensitivity [1–3].Compared with monatomic projectiles of comparable mass and energy, polyatomic projectiles lead to …

WebTime of flight ( ToF) is the measurement of the time taken by an object, particle or wave (be it acoustic, electromagnetic, etc.) to travel a distance through a medium. This information can then be used to measure velocity or path length, or as a way to learn about the particle or medium's properties (such as composition or flow rate). Web4 okt. 2024 · As an IMS technology, time-of-flight–secondary ion mass spectrometry (TOF–SIMS) provides both mass spectra (chemical information) and ion images (spatial information) for biomolecules on ... Web18 feb. 2016 · Conventionally, ToF-SIMS measurements rely on signal averaging (SA) over multiple experimental cycles to maximise the signal-to-noise ratio and resulting sensitivity. Each cycle consists of a short (nanosecond) primary ion pulse, followed by the measurement of the flight time (up to 0.2 milliseconds) of secondary ions, ejected from … irm referti online
