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 ...

Learn how to verify research-grade peptide purity using HPLC, mass spectrometry, and Certificates of Analysis, plus the key ...

Researchers analyzing protein-based drugs with mass spectrometry must handle challenges including analyte ion distribution over multiple charge states. The ZenoTOF 7600 system is a high-resolution ...
