✦ Synopsis

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, -CH3NHzCO)+' through elimination of CO+' from [CH,NH,CO]+', and the adduct [M f 75]", [ROCONHCH, * OCONH,CH,]+', is also obtained.

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

Various esters of choline and carnitine have been shown to undergo fragmentation dependent on both the structures of the molecules and the vapor and block temperatures when subjected to thermospray ionization mass spectrometry. The fragments observed vary with the structure of tbe ester portion and
