The electrospray ionisation (ESI) of selected coumarin derivatives and their subsequent fragmentation using an ion trap mass spectrometer have been investigated. Sequential product ion fragmentation experiments (MS(n)) were performed in order to elucidate the degradation pathways for these compounds

The molecular ion of n-butylbenzene (m/z 134) is one of the most widely used thermometer molecules in mass spectrometry, the ratio of abundances of its competitive two-channel decomposition products, C,H; (m/z 91) and (m/z 92), serving as a measure of the average internal energy deposited into the
## Electrospray ionization (ESI) tandem mass spectrometry collision-induced dissociation (CID) fragmentation processes of a series of nitroaromatic, nitramine and nitrate ester explosives were studied in the negative-ion mode using daughter-ion, parent-ion and neutral loss scans. 2,4,6-Trinitrotolu
The feasibility of a technique to confirm the presence of residues from seven b-lactam antibiotics in bovine milk has been demonstrated. The technique makes use of electrospray ionization and tandem ion trap mass spectrometry. Residues are first extracted from milk by reversed-phase solid phase extr
