The TOF component can analyze the entire mass spectrum in one second, with a mass resolution of over 5000 and a maximum of 8000. Even isobaric substances can be separated and identified, there is ...
Sekundärionen-Massenspektrometrie – Wikipedia
WebbSekundärionen-Massenspektrometrie (SIMS) ist eine Methode der Oberflächenphysik / Oberflächenchemie, mit der die Zusammensetzung einer Probe analysiert werden kann; sie stellt somit eine spezielle Form der Massenspektrometrie dar. Wie Sekundär-Neutralteilchen-Massenspektrometrie (SNMS), Rutherford Backscattering Spectrometry … Webb13 aug. 2024 · All investigations were carried out using an online PTR-ToF-MS instrument equipped with a modular IF (PTR-TOF 1000 ultra, IONICON Analytik GmbH, Innsbruck, Austria; first-generation model (2024)). Figure 1 shows a schematic view of the instrument. The general working principle of PTR-ToF-MS has been described in several studies [4, 5]. ghs homecoming

WebbThe TOF adds simultaneous all-element detection, linear response and mass resolving power >6000, while maintaining QMS-equivalent sensitivity. With high-speed mass spectral acquisition and simultaneous analysis of all isotopes, the icpTOF is the ideal ICP-MS detector for multi-element single particle analysis or fast laser ablation imaging . WebbDescription. The PTR-TOF 8000 combines the very low online detection limit (less than 5 pptv) with the speed and resolution of a time of flight mass spectrometer. The TOF component can analyze the entire mass spectrum in one second, with a mass resolution of over 2000 and a maximum of 8000. Even isobaric substances can be separated and ...
