The analysis of peptides and proteins as well as the grander scope of proteomics (large
scale study of proteins) has been advanced by the development of a versatile array of ion …

Mass spectrometry (MS) has played an increasingly important role in the identification and
structural and functional characterization of proteins. In particular, the use of tandem mass …

A kiloelectronvolt beam of helium ions is used to ionize and fragment precursor peptide ions
starting in the 1+ charge state. The electron affinity of helium cations (24.6 eV) exceeds the …

Highly bond-specific fragmentation of oligopeptides induced by swift heavy ion (SHI)
irradiation was investigated by means of mass spectrometry. In pronounced contrast to …

Dissociation of proteins and peptides by 193 nm ultraviolet photodissociation (UVPD) has
gained momentum in proteomic studies because of the diversity of backbone fragments that …

The fragmentation behavior of three peptides (RGAFSTFGAS, GAFSTFGASR, and
GAFSTFGASS) was evaluated by collisional activated dissociation (CAD), higher energy …

The identification of molecular ions produced by MALDI or ESI strongly relies on their
fragmentation to structurally informative fragments. The widely diffused fragmentation …

The first application of light‐emitting diodes (LEDs) for ultraviolet photodissociation (UVPD)
mass spectrometry is reported. LEDs provide a compact, low cost light source and have …

The recent surge in the analysis of biomolecules has driven the need for robust, versatile,
sensitive, and accurate techniques such as tandem mass spectrometry for compound …

Electron capture dissociation (ECD) was first reported in 1998 by Zubarev, Kelleher, and
McLafferty. 1 ECD produces odd-electron ions by the recombination of a low-energy …
