A tandem quadrupole mass spectrometer is used to create ion species from a sample, separate one individual ion species, fragment it, and obtain the mass spectrum of the fragments. Practicability of the Selected Ion Fragmentation Tandem Quadrupole Mass Spectrometer SIFT QMS is experimentally demonstrated. Normally large ion losses due to scattering in the collision-induced dissociation CID process are eliminated by performing CID in a RF-only quadrupole. CID spectra with unit mass resolution are produced by the quadrupole mass filters. The CID spectrum of each component of a cyclohexane mixture containing three minor components is presented. Potential applications of SIFT QMS in mixture analysis and structure elucidation are discussed. Author
