Chemical Ionization Methods in Selective Chromatography–Mass Spectrometry of Alkylphosphonic Acid Derivatives

Control over the destruction of chemical weapons requires analyses of various complex samples like water, soils, paint coats, mechanical rubber articles, vegetation, etc. aimed at the detection and determination of toxic substances related to chemical weapons. This paper considers the developed procedures of chromatographic–mass spectrometric analysis with positive- and negative-ion chemical ionization. These procedures eliminate false positive and negative results in determining complex samples containing trace organophosphorus compounds.
