Identification of Stable Phosphorus-Containing Combustion Byproducts by Gas Chromatography/Mass Spectrometry Preceded by Derivatization

摘要

The technique of gas chromatography/mass spectrometry preceded by trimethylsilyl derivatization has been applied to identify combustion byproducts from a premixed CH_4/O_2/N_2 flame doped with dimethyl methylphosphonate, a simulant for organophosphorus chemical warfare agents. The fol- lowing species or their derivatization products were detected: dimethyl methylphosphonate, methyl methyphosphonate, dimethyl phosphate, monomethyl phosphate, methylphosphonic acid, or- thophosphoric acid, phosphorous acid, and phosphonic acid.
