Here, we use a combination of infrared ion spectroscopy and quantum‐chemical calculations to assign the structures of two ETD‐generated w ‐type fragment ions. These ions are …

In mass spectrometry, fragmentation is the dissociation of energetically unstable molecular ions formed from passing the molecules mass spectrum.

In low energy CID (i.e. collision induced dissociation in a triple quadrupole or an ion trap) a peptide carrying a positive charge fragments mainly along its backbone, generating …

For insulin-B chain, all series of a-, b-, y-, c- and z-ions, as well as a number of w- and d-ions, are detected simultaneously in a single mass spectrum covering the full 30 amino acid sequence. …

Each observed MSMS spectrum has a corresponding molecular ion [M+nH]n+. For ion trap data, ions are selected from the known or virtual proteome that are within 1 Da. These are then …

What fragment ions are characteristics for glucuronide conjugates? What happens with aliphatic sulfates in MS/MS? Aliphatic and aromatic sulfate conjugates behave differently in MS/MS …
