O-Isopropylidene and O-benzylidene acetals of common 2,6-anhydro-1-deoxy-1-nitroalditols (b-D-glycopyranosylnitromethanes) derived from D-glucose, D-galactose and D-mannose were studied by electron ionization (EI) mass spectrometry. Fragment pathways of the title compounds were studied using accurat

A family of 12 (7 saturated and 5 unsaturated) long chain fatty acid N-(2-hydroxyethyl)amides has been investigated by electron ionization (EI) and positive-ion chemical ionization (PICI) mass spectrometry. This paper presents the mass spectra and structures of the main ions obtained by EI and PICI
Positive-ion electron ionization (EI), methane chemical ionization (CI) and collision-induced dissociation (CID) mass spectra are reported for a series of pyridone-imines generated from 1-alkyl substituted aminopyridinium salts in a direct-probe inlet. The series comprises 1-methyl-2-imino-and 1-eth
Atmospheric pressure chemical ionization tandem mass spectrometry was used to study the gas-phase reactions of protonated a-and b-aspartame. The results show that under collision-induced dissociation conditions, these ions undergo dehydration to form anhydro derivatives in addition to carbon-carbon
