WebThe effect that charge state has on the collision-induced dissociation (CID) of peptide ions is examined in detail for several representative peptides under high-energy collision conditions. The CID spectra of singly and doubly charged precursor ions (generated by fast-atom bombardment and electrospray ionization, respectively) are compared for several … Web1 de jun. de 1992 · High energy collision-induced dissociation (CID) techniques were applied for structural elucidation of alkali-metal ion adducts of crown ethers. The CID of alkali-metal adducts of tetraglyme and hexaethylene glycol were also evaluated to contrast the fragmentation pathways of the cyclic ethers with those of acyclic analogs.

Web20 de mar. de 2024 · These are known to be the dominant dissociation channels for PAHs following photo-absorption processes or low-energy collision-induced dissociation experiments. We have also shown that the H/C 2 H 2 ratio depends on the PAH, on energy and on time and that it increases with the size of the PAH, which seems in line with … WebThe absolute cross section for collision induced dissociation is measured over a wide range of kinetic energies (28--109 kcal/mol) and incident angles of Ne, Ar, and Kr atom … ray white westport
