Webb1 mars 2024 · The time-of-flight principle is based on measuring the time it takes for a wave to travel from a source (a time-of-flight sensor) to an object and back. Based on that data – as well as some knowledge of maths and physics (such as wave propagation) – you can establish the distance of that object from the source. WebbThermo Fisher Scientific

WebbThe Orbitrap is an ion trap mass analyzer. It consists of two outer electrodes and a central electrode, which enable it to act as both an analyzer and detector. Ions entering the Orbitrap are captured through “electrodynamic squeezing,” after which they oscillate around the central electrode and in between the two outer electrodes.
