The reliability of library matching with the WRTMD and libraries derived from the WRTMD by substituting the original reference spectra with instrument-specific library spectra is shown by sensitivity versus collision energy for a a QqTOF instrument, b a Q-Orbitrap instrument with HCD, c a LIT-Orbitrap instrument with HCD, and d a LIT-Orbitrap instrument with CID, respectively. The collision energies are given in eV for the QqTOFs and NCE for the Orbitraps. a–c Reliable matches in a wide CE range, while d shows that the optimal CE window is smaller for LIT-Orbitrap instrument with CID
