Dual-Polarity Linear Ion Trap Femtosecond Laser-Induced Ionisation/Dissociation Mass Spectroscopy for Proteomics

Not Accessible

Your library or personal account may give you access

Abstract

Peptides are irradiated by femtosecond near-infrared pulses, initiating tunnel ionisation and non-ergodic molecular dissociation. Mass spectrometric analysis of the fragments gives unique structural and dynamical information for femtosecond molecular dynamics research and bioanalytical applications.
