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 ...

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 ...

Can you describe how the untargeted ultrahigh-performance liquid chromatography–high resolution tandem mass spectrometry (UHPLC–HRMS/MS) workflow was designed to capture both known salicylates and ...

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 ...

Sensitivity is a fundamental performance characteristic of a mass spectrometer. Increasingly higher sensitivities are in constant demand in order to characterize and quantify analytes that are at an ...
