Abstract : The method is presented for the accurate determination of trinitrotoluene (TNT) concentration in NESST (nonhazardous explosive for security training and testing) samples. The technique involves chloroform solvent extraction of sand adsorbed TNT, followed by quantitative analysis using liquid state carbon-13 nuclear magnetic resonance (NMR). The concentration of TNT is determined by comparison of integrated peak intensities using an appropriate reference compound. Samples # KTN-01-AA and # N-01-AA were found to contain 7.1 +/- 0.2% TNT and 5.3 +/- 0.2% TNT, respectively.
