The Analysis and Characterization of TNT Using Liquid Chromatography with Photodiode Array Detection
The forensic characterization of various samples of TNT is described. The analysis technique consists of extraction followed by normal phase liquid chromatography with photodiode array detection. The samples are examined by enhancing the minor components and impurities left over from manufacture, and using these components as points of comparison. Initial attempts to order the data using spectral searching and pattern recognition techniques are described.
