On-line high performance liquid chromatography (HPLC)-negative ion chemical ionization (NCI) mass spectrometry has been used for the analysis of explosives mixtures. The liquid chromatography-mass spectrometry (LC/MS) interface used was a commercial direct liquid introduction interface allowing about 1% of the solvent/sample effluent into the ion source. The HPLC mobile phases were acetronitrile/water (50:50) and methanol/water (50:50), which served also as NCI reagent gases. Standard mixtures containing 2,4,6-trinitrotoluene (TNT), cyclonite (RDX), tetryl, and pentaerythritol tetranitrate (PETN), and a military explosive, tetrytol, have been analyzed by the LC/MS system. The minimum detectable amount of TNT was 100 ng injected on column, or approximately 1 ng to the ion source. |
