It is thus possible to detect and analyse the mass of all of the precursors of a given fragment, so long as they yield a metastable or collision-induced fragmentation. 

Collision-induced fragmentation of Ceo" (n = 1 3) with the noble gases helium and neon at high energy (typically 6keV) results in the formation of encapsulated products, e g. [He C6o]"" The retention of the gas atoms in the fragmentation products [He C2m]" (2w = 58, 56, 54, etc.) is consistent with endohedral complex formulation. Furthermore, [He C6o] has been neutralized in the gas phase to produce He C6o (lifetime >90 p,s), which was then successfully... 

Selective detection of posttranslational modifications is possible through collision-induced formation of low-mass fragment ions that serve as selective markers for the modifications of interest. Collision-induced fragmentation, which is turned on while scanning the lower mass range, is turned off during the remainder of the scan (e.g. m/z 400-2400). In this way peptide molecular weight information and modification-selective, low-mass marker ions are detected in the...
