AB  - Gas chromatography/mass spectrometry (GC/MS) is a "workhorse" instrument for 
      chemical analysis, but it can be limited in its ability to differentiate 
      structurally similar compounds. The coupling of GC to vacuum ultraviolet (VUV) 
      spectroscopy is a recently developed technique with the potential for increased 
      detection specificity. To date, GC/VUV has been demonstrated in the analysis of 
      volatile organic compounds, petroleum products, aroma compounds, pharmaceuticals, 
      illegal drugs, and lipids. This paper is the first to report on the utility of 
      GC/VUV for explosives analysis in general, and the first to report on thermal 
      degradation within the VUV cell and its analytical utility. The general figures 
      of merit and performance of GC/VUV were evaluated with authentic standards of 
      nitrate ester explosives (e.g., nitroglycerine (NG), ethylene glycol dinitrate 
      (EGDN), pentaerythritol tetranitrate (PETN), and erythritol tetranitrate (ETN)). 
      In addition, the explosive analytes were thermally degraded in the VUV cell, 
      yielding reproducible, complex and characteristic mixtures of gas phase products 
      (e.g., nitric oxide, carbon monoxide, and formaldehyde). The relative amounts of 
      the degradation products were estimated via spectral subtraction of library 
      spectra. Lastly, GC/VUV was used to analyze milligram quantities of intact and 
      burned samples of double-base smokeless powders containing nitroglycerine, 
      diphenylamine, ethyl centralite, and dibutylphthalate.
