Examples of MS/MS spectra for two representative metabolites of a plant extract using a ramp of collision energy weighted by m/z (5–40 V at m/z 50 and 20–70 V at m/z 1200) or a stepped collision energy (10‐20‐30‐40‐50 V). In both cases, the ramped collision energy provides more informative fragments than the stepped collision energy
