Webb1 apr. 2004 · There is no inherent low-mass cutoff in the product ion spectra of a Q TRAP™ instrument because the fragmentation and the ion-trapping steps are spatially separated. In conventional 3D ion traps, the precursor ion and the lowest mass fragment ion must be stable simultaneously in the trap, which produces a low-mass cutoff in the resulting … WebbPeptide Mass Fingerprinting (PMF), also known as mass fingerprinting, was developed in 1993.
