TimeofFlightsäteen
TimeofFlightsäteen refers to a phenomenon observed in certain time-of-flight mass spectrometry experiments. Specifically, it arises when ions or molecules within a sample have a distribution of velocities that leads to a broadening of the signal peak in the mass spectrum. This broadening is not due to variations in mass-to-charge ratio, but rather to the differing transit times of particles with the same mass but different initial speeds through the flight tube of the spectrometer.
In a typical time-of-flight mass spectrometer, ions are accelerated by an electric field and then travel through
This velocity spread causes ions with the same mass to spread out in their arrival times, leading
