Abstract:The paper deals with possible applications of the connection of liquid
chromatography with atmospheric pressure chemical ionization (APCI) mass
spectrometry (Agilent 1100 series LS-MSD system) and gas chromatography
with electron capture detector (GC-ECD) in the analysis of some common available
or improvised explosives. The analysis of selected types of individual explosives,
2,4,6-trinitrotoluene (TNT), 1,3,5-trinitroso-1,3,5-triazinane (TMTA) and analysis
of their mixtures (TNT/TMTA and RDX/TMTA) in their post-explosion residues
on the basis of generated characteristic mass spectra by using LC-MSD system is
the aim of this work. Post-explosion analysis of TMTA and its explosive mixtures
can be similarly complicated, like that of the well-known plastic explosive on the
basis of pentaerythritol tetranitrate, Semtex-1A.
