For more than 30 years, electron ionization mass spectrometry (EIMS) has played a key role in the structural determination of small biological compounds, largely because it has three advantages to offer: very high sensitivity compared to other structural methods, such as nuclear magnetic resonance and infrared spectrometry, the possibility for analysis

Tandem mass spectrometry: A primer
Journal of Mass Spectrometry, 1996Tandem mass spectrometry (MS/MS) employs two stages of mass analysis in order to examine selectively the fragmentation of particular ions in a mixture of ions. The various types of instruments which can be used to perform this experiment are described, including those based on separation of the mass-analysis events in time and those based on ...

Tetrodotoxin (TTX), a powerful sodium channel blocker, usually exists as a mixture of its analogs (TTXs) in natural sources. Due to the structural variation, some analogs are difficult to detect using the postcolumn liquid chromatography-fluorescent detection (LC-FLD) system.

Multiplexed and data-independent tandem mass spectrometry for global proteome profiling.
Mass spectrometry reviews (Print), 2014One of the most important early developments in the field of proteomics was the advent of automated data acquisition routines that allowed high-throughput unattended data acquisition during HPLC introduction of peptide mixtures to a tandem mass ...

Electron ionization mass spectra show a wealth of fragment ion peaks allowing to retrieve structural information, often though at the expense of abundance of the molecular ion. For decades, EI has served as the one and only ionization method of organic mass spectrometry.

Tandem mass spectrometry of polyglycols
International Journal of Mass Spectrometry and Ion Processes, 1989Abstract Fast atom bombardment—tandem mass spectrometry has been carried out with low molecular weight samples of poly(ethylene glycol) and poly(propylene glycol). Sodium attachment ions generated from either polymer were found to be extremely stable.

Electrospray tandem mass spectrometry of epipolythiodioxopiperazines
Journal of Mass Spectrometry, 2007AbstractLow‐energy collision‐induced electrospray ionization tandem mass spectrometry ESI‐CID‐MS/MS (in the positive ion mode) was used for the structural characterization of a series of five representative epioplythiodioxopipreazines: dethiotetra(methylthio)chemotin, chaetocochins A, B and C, and chemotin isolated from the fungus Chaetomium cochliodes.
