Spectra of leucine enkephalin (YGGFL) monomer fragmented with A) 35 eV SID using the tilted-surface/ion carpet SID device and B) 20 eV CID in the trap cell. Because of the different effective target masses, collision energies were chosen to ~match precursor reduction rather than showing the same collision energy. SID experiments required analyte concentrations equal to and acquisition times comparable to CID. Additional energies and a comparison to the original 10-lens device are shown in Figures S6 and S7.
