Simultaneous identification and quantification of nitro-containing explosives by advanced chemometric data treatment of cyclic voltammetry at screen-printed electrodes

► Good discrimination of pure explosive compounds and their most common mixtures. ► Simultaneous determination of hexahydro-1,3,5-trinitro-1,3,5-triazine, 2,4,6-trinitrotoluene and pentaerythritol tetranitrate mixtures by means of ANNs. ► Generation of distinct signatures from a bare screen-printed carbon electrode. ► Use of discrete wavelet transform for voltammetric data compression. ► Rapid and low-cost field-deployable detection of explosive compounds.
