Abstract
The major sample components in dichloromethane extracts of munitions grade tabun decontaminated with methanol/potassium hydroxide, including nine compounds not previously associated with tabun, were identified following capillary column GC-MS analysis. Electron impact fragmentation ions provided valuable structural information for the unknown sample components, but the presence of little or no molecular ion information for many of the unknown components made identification difficult. Ammonia chemical ionization analysis was required to provide the complementary molecular information necessary for identification or tentaive identificaton of these compounds. All the major sample components exhibited significant (M+H) + and (M+NH4) + pseudo-molecular ions and in some cases structurally significant C1 fragmentation ions during capillary column ammonia chemical ionization GC-MS analysis.
