A paper by A. Roxana Nicolaescu, Serim Research Corporation, USA
Fertilizers are readily available, cheap, and have been used in terrorist incidents all over the globe, as precursors to homemade explosives (HMEs) or as components of improvised explosive devices (IEDs). The critical need for specifically identifying the source of explosive materials in the field by EOD personnel is obvious, and has been emphasized by government officials.
A paper-based colorimetric detection device (DISCERN®) has been developed for the on-site identification of compounds used to make home-made explosives. It was designed to detect and identify up to five separate threats using one sample. The unknown powder is wetted with water and transferred with a foam swab to the indicator pads of the device. Based on the specific chemical reactions, the color pattern distinguishes within one minute and in one step the presence of perchlorates, or urea nitrate, or ammonium nitrate, or black powder, or chlorates and organic peroxides.
