Low-energy collision induced

The hybrid has other advantages of sensitivity, low signal-to-noise ratio, fast switching between MS and MS/MS modes, use with continuous or pulsed ion sources, and use with high- or low-energy collision-induced ion decomposition.

The main principles of de novo sequencing will be discussed here using a few d spectra that were acquired using an ion trap mass spectrometer equipped with an electrospray ion source, under low energy collision induced dissociation (CID). 

Huang and Freiser (132, 133) were able to prepare exohedral metal C60 ions [MC60]+ by direct reaction of the bare metal ions Fe+, Ni+, Co+, Cu+, Rh+, and La+ with Cgo vapor produced from a heated probe. The [MC60]+ ions when subjected to low-energy collision-induced dissociation with argon all produced the Cg0 ion. These results show that the metal ions attach to the outer surface of C60. The exohedral metallofullerene ions differ from the endohedral metallofullerenes produced by laser ablation of metal oxide-graphite mixtures and support the observations of Smalley and co-workers (148) who found that endohedral metallofullerene ions dissociate by loss of C2 units.

The particular use of mass spectrometry techniques was of fundamental relevance in the structural determinations of CMHs from different species, including analytical variations as fast atom bombardment mass spectrometry (FAB/MS), electronspray ionization (ESI-MS) and low energy collision-induced dissociation tandem mass spectrometry (ESI-... 

Quadrupole mass analysers provide good reproducibility and represent a relatively small and low-cost system. Low-energy collision-induced dissociation (CID) MS/MS experiments are enabled in triple quadrupole and hybrid mass spectrometers and have efficient conversion of precursor to product. These spectra depend strongly on energy, collision gas, pressure, and other factors. Quadmpole mass...

Figure 3.5 Nomenclature for peptide sequencing. Fragments resulting from backbone cleavages are mainly observed when MALDI peptide ions are fragmented in low-energy collision-induced dissociation (CID) tandem mass spectrometers. Of these, the cleavage at the amide bond will be most efficiently cleaved, resulting in y- and b-ions, depending on which part of the peptide will...
