Tandem mass spectrometry is a powerful tool in proteomics. By ionizing peptides and then fragmenting those ions into smaller product ions, researchers can determine the biomolecules’ amino acid ...

Effective protein characterization depends on the precise isolation and fragmentation of peptide ions within the mass spectrometer, typically coupled with liquid chromatography (LC-MS/MS). In a ...

Ions are accumulated in the Zeno trap before being pulsed rapidly into the TOF, meaning up to 20x more fragment ions can be detected. Enabled by a new level of sensitivity, each MS/MS experiment ...

TOF-SIMS is a mass spectrometry technique in which a solid sample is bombarded by ions, which then release fragments of the surface molecules. The material ejected from the sample typically is from ...

For glycopeptide characterization, mass spectrometry has arisen as the go-to methodology. As well as the instrumental arrangement, a suitable software solution is essential to enable glycopeptide ...

Electron ionization (EI) is a hard ionization method that is typically used with gas chromatography-mass spectrometry (GC-MS). The mass spectral fragmentation patterns generated by EI are used for ...
