The study demonstrates how Gas Chromatography/Mass Spectrometry (GC/MS) and Liquid
Chromatography/Mass Spectrometry (LC/MS) techniques are applied for identification of sarin type of nerve
agents. A brief historical review of Chemical Weapon Convention (CWC) has been presented. GC/MS and
LC/MS as analytical techniques have been used for the identification of Propyl isopropylphosphonofluoridate
and its degradation products. W hile the Propyl isopropylphosphonofluoridate was identified with the GC/MS,
its degradation products were identified with LC/MS. Analysis of the propyl isopropylphosphonofluoridate with
the GC/MS produced a mass spectrum with a base ion with charge to mass ratio of 127. The mass spectrum
of propyl isopropylphosphonate using LC/MS produced a deprotonated molecular ion at mass to charge ratio
of 165, while a similar spectrum of isopropylphosphonic acid produced a deprotonated molecular ion with mass
to charge ratio of 123.
Key words: Chemical weapon convention, fragmentation, ionization, molecular ion, nerve agents, spectrum,
