Abstract

In an initial investigation of the potential utility of chemical ionization (CI) mass spectrometry of selected of chemical warfare agents using metal ions, the reactions of manganese ions with chloroalkyl sulfides analogs organophosphonates have been followed in a Fourier transform mass spectrometer. Mn+ ions, produced and by UV laser radiation focused on a stainless steel target, react rapidly with each molecule studied to provide mass spectra. The manganese ion CI mass spectra are compared to mass spectra obtained via characteristic electron impact (EI) and methane CI.
