UNSPECIFIED. (1991) COLLISION-INDUCED DECOMPOSITION OF PEPTIDES - AN INVESTIGATION INTO THE EFFECT OF COLLISION GAS-PRESSURE ON TRANSLATIONAL ENERGY-LOSSES. ORGANIC MASS SPECTROMETRY, 26 (5). pp. 395-401. ISSN 0030-493XFull text not available from this repository.
The dependence on the gas pressure of translational energy losses, DELTA-E, suffered by incident ions in collision with helium target gas atoms was investigated for the [M + Na] + ion of valinomycin. DELTA-E was measured from the fragment ion peak positions in the mass-analysed ion kinetic energy (MIKE) spectra. The variation of DELTA-E with target gas pressure was found to be different for different fragment ions. The implications of the results for the number of collisions which may occur under normal collision-induced decomposition conditions (30-40% transmission) are discussed.
