Rapid identification, confirmation, and quantitation using an open-air ion source coupled to a time-of-flight mass spectrometer
… ability to identify and confirm a compound using mass spectrometry usually involves time consuming sample preparation and method development. The open-air ion source DART (Direct Analysis in Real Time) can ionize compounds in the gas, solid, or liquid phase without chromatography or sample …

The mass spectra and correlations with structure for some 1-(5-ethyl-2-thienyl)-1-thiaalkanes
The mass spectra of fifteen members of the 1-(5-ethyl-2-thienyl)-1-thiaalkanes have been obtained. Fragmentation paths, rearrangement mechanisms supported by low ionization voltage data have been discussed. The parent peaks are moderately strong. The rearrangement ion at m/e 144 is prominent for …

Mass spectrometry of crosslinked peptides
… of crosslinked peptides by analysing their mass spectrometric fragmentation behaviour and leveraging the knowledge gained for the development of advanced acquisition methods. First, I investigate the influence of the employed fragmentation method and parameters on peptides crosslinked with …

Structural elucidation of glycerophospholipids using metastable atom-activated dissociation mass spectrometry (MAD-MS)
… are analyzed through hyphenated chromatography-mass spectrometry instruments and especially using collision-induced dissociation (CID). Low-energy CID typically produces both headgroup and complete fatty acid chain loss, whereas high energy CID causes extensive fatty acid chain fragmentation. …
