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 ...

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 ...

α-Cleavage – The homolytic fragmentation is induced by a radical cation located at a hetero atom. Functional groups can be arranged by their ability to induce α-Cleavages. Allyl cleavage – Homolytic ...

What will you learn on this course? This course is an introduction to mass spectral interpretation, aimed at presenting the fundamental tools and rules when examining high quality full-scan GC-MS data ...
