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 ...

Meridion, developers of advanced mass spectrometry instrumentation, has announced the availability of its patented ...

The process of protein identification typically begins with a bottom-up approach, where proteins are enzymatically digested—most commonly with trypsin—into smaller peptides. These peptides are ...

Mass spectrometry has become central to modern proteomics workflows, enabling high-throughput protein identification, quantification, and characterization. The commonly used mass spectrometers for ...

A recent study explored rapid evaporative ionization mass spectrometry (REIMS) as a high-throughput, real-time alternative. By analyzing metabolomic fingerprints from pig neck fat, REIMS was combined ...
