WebAtomic Structure TOF - SCT Page 2 of 17 (d) In a TOF mass spectrometer the time of flight, t, of an ion is shown by the equation In this equation d is the length of the flight tube, m … Time-of-flight mass spectrometry (TOFMS) is a method of mass spectrometry in which an ion's mass-to-charge ratio is determined by a time of flight measurement. Ions are accelerated by an electric field of known strength. This acceleration results in an ion having the same kinetic energy as any other ion that has the same charge. The velocity of the ion depends on the mass-to-charge ratio (hea…
