The uv spectra of chemical agents GA, GB, GD, VX, HD, and L and common agent simulants have been measured in cyclohexane solution from 350 to 200 nm. The purity of the agents, measured by gas chromatographic analysis, was in general >96%. At 230 nm, the strength of the uv absorption followed the general trend L > VX > GA > HD > GD > GB > DMMP. Except for HD and L, agent spectra lacked characteristic features that will be useful for remote detection by uv sensors.

Analytical procedures were developed that use gas chromatography and gas chromatography/mass spectrometry techniques to determine the purity of commercially available and purified liquid and gaseous tetrakls(dlmethylamlno)ethylene (TMAE). More than 20 components were detected; most were Identified from their mass spectral fragmentation patterns. The six major TMAE Impurities were dimethylamine,
