A library of atmospheric pressure ionization daughter ion mass spectra based on wideband excitation in an ion trap mass spectrometer

A searchable library of MS/MS spectra obtained using a quadrupole ion trap mass spectrometer and electrospray or atmospheric pressure chemical ionizat ion is presented. The application of wideband excitation (activation) and n ormalized collision energy leads to highly reproducible mass spectra which are searched using the NIST algorithm, Flow injection and LC/MS/MS applicat ions of this powerful technique in the biomedical (diastereoisomeric steroi ds, morphine glucuronides, isovalerylcarnitine) and environmental (pirimica rb and desmethyl-pirimicarb) areas are described.
