    • In a color reaction method for detecting particular classes of explosives, a sample from a suspect source is subjected serially to the indicated reagents in the liquid phase, the reagents after the first being applied only if no color reaction has been obtained in the preceding test. The second and third reagents only are applied in presence of the preceding reagent(s). The first reagent is an alkaline solution of a diazotizable aminoaromatic azo-dye precursor, which detects nitroaromatic explosives. The second reagent is a strongly acidic reagent containing a nitrate to nitrite ion reducing agent and a diazo-coupler, which detects organic nitrates and nitramines. The third reagent is zinc powder suspended in a liquid, which detects inorganic nitrates. The fourth reagent is an aniline salt in a homogeneous strongly acidic solution including a water-miscible organic solvent, which detects chlorates and bromates. The invention includes also a test kit for use in the method.
    • 在用于检测特定类别的爆炸物的彩色反应方法中,将来自可疑源的样品连续地进入液相中指定的试剂,仅在前一试验中没有获得显色反应的情况下,首次施用试剂。 第二和第三试剂仅在前一试剂存在下使用。 第一种试剂是可重氮化氨基偶氮染料前体的碱性溶液,其可以检测硝基芳族炸药。 第二种试剂是含有硝酸根至亚硝酸根离子还原剂和重氮偶合剂的强酸性试剂,其检测有机硝酸盐和硝胺。 第三试剂是悬浮在液体中的锌粉,其检测无机硝酸盐。 第四试剂是均匀强酸性溶液中的苯胺盐,其包括水混溶性有机溶剂,其检测氯酸盐和溴酸盐。 本发明还包括用于该方法的测试试剂盒。
