Abstract
A homologous series of phosphate esters (trimethyl phosphate, triethyl phosphate, tripropyl phosphate and tributyl phosphate), often employed as chemical simulants for chemical warfare agents, were characterized by tandem mass spectrometry under EI conditions. The daughter spectra for the principal EI ions of each phosphate ester were acquired by stepping the collisional activated dissociation cell energy from 1 eV to 100 eV (laboratory scale) in 1 eV increments with residual air and argon target gases. A standardized MS/MS setup procedure was established and the reproducibility of daughter scanning over the long and short term was evaluated. The sensitivity of capillary column GC-MS/MS was excellent and approximated that achieved during full scanning capillary column GC-MS analysis under EI conditions.
