Abstract
The effects of ion kinetic energy upon the low-energy collision-induced dissociation (CID) process in triple quadrupole mass spectrometry (MS/MS) are investigated. Energy-resolved CID breakdown curves are compared to those from quasi-equilibrium theory (QET) and angle-resolved mass spectrometry. The use of breakdown curves for the differentiation of isomeric ion structures is also investigated In addition. associative collisions with reactive collision gases are studied by energy-resolved MS/MS. These techniques provide a better understanding of the low-energy collision process in MS/MS and are essential in determining standard conditions for recording MS/MS library spectra
