The mass spectra of unlabelled and specifically labelled triterpenes and derivatives were recorded using thermospray liquid chromatography (TSP-LC) and electron impact (EI) ionization. These mass spectra were used for the development of assays to characterize the products from the in vitro oxidative

The thermospray mass spectrometry (TSP/MS) of five N-methylcarbamates is presented. This is the first time that ions other than [M + HI+ and [M + NHJ+ have been reported using positive TSP/MS. Protonation of ROCONHCH, yields the [CH3NHzCO]+' ion, with formation of the ion-molecule adduct [ROCONHCH,
Five metal complex azo compounds were analyzed using negative-ion electrospray ionization mass spectrometry (ESI-MS). Mass spectra of all compounds yield intense peaks corresponding to [M - H](-) ions without any fragmentation, where M denotes the neutral compound with a proton as the counterion. Un
Thermospray liquid chromatography/mass spectrometry using a double-focusing magnetic sector mass spectrometer has been studied. The quality of the thermospray mass spectra were often a function of the solvent mixture used, and use of gradients affected the quality of some thermospray mass spectra. H
