WebTime-of-Flight Secondary Ion Mass Spectrometry (TOF-SIMS) provides elemental, chemical state, and molecular information from surfaces of solid materials. The average depth of analysis for a TOF-SIMS measurement is approximately 1 nm. Physical Electronics TOF-SIMS instruments provide an ultimate spatial resolution of less than 0.1 µm. WebTOF-SIMS and record intensities of more than 100 ions per pulse and mass interval with excellent linearity and reproducibility. The maximum count rate is no longer limited by the …

Webwhen providing our ioniTOF for your experimental TOF set-ups in academic research or the development of commercial end-user TOF systems. THE SOLUTION FOR REAL-TIME … WebBoth variations distinguish different m/z value ions by measuring the time taken for an ion to travel from the ion source to the detector. a. A calibration ion with m/z =256 mass units is measured using a linear TOF-MS to have a flight time of 76 μs. Determine the m/z value for an ion which is seen to have a flight time of 107. μs. Web11 apr. 2024 · In this study, the sensitivities of phospholipids mixed with aliphatic carboxylic acids were investigated using Bi-cluster time-of-flight SIMS (TOF-SIMS). Trans -aconitic acid (tri-carboxylic acid) and citric acid (hydroxycarboxylic acid) were used as the matrices. 2,5-Dihydroxybenzoic acid (DHB), which is a typical aromatic MALDI matrix, was selected as … how does a turn and bank indicator work
