Figure 3

Panel A. Triple quadrupole instrument. Ions are selected in Q1, fragmented in Q2, and daughter ions scanned out in A3. Panel B. Fourier transform Orbitrap MS. Ion trajectories in an Orbitrap mass spectrometer Panel C. Time-of-Flight MS. In the example shown, Matrix-assisted laser desorption ionization is used to generate ions that are selected in an electric field and m/z determined based on time taken to reach the detector.
