Introduction To mass Spectrometry: Protein/peptide ...
The “time of flight” (t) depends on the mass of the ion (m), where t = (m/2eV)1/2.D V is the applied potential and D is the flight tube distance. For a given instrument, the flight time varies as the square root of the mass of the ion. Resolution 2 x 104 No upper limit of mass Scan times ~ 1 msec, good for LC-MSMS Oscilloscope to time ion ...
