    • In a method for detecting particular classes of explosives, a suspect sample is subjected serially to reagents (1), (2), (3) and (4) in the liquid phase, the reagents after the first being applied only if no color reaction has been obtained in the preceding test, while reagents (2) and (3) only are applied in presence of the preceding reagent(s). (1) is an alkaline solution of a diazotizable aminoaromatic azo-dye precursor (for nitroaromatic explosives). (2) is a strongly acidic reagent containing a nitrate to nitrite ion reducing agent and a diazo-coupler (for organic nitrates and nitramines). (3) is zinc powder suspended in a liquid comprising at least one water-miscible solvent (for inorganic nitrates). (4) is an aniline salt in a homogeneous strongly acidic solution including a water-miscible organic solvent (for chlorates and bromates). The invention includes also a test kit, as well as reagents (3) and (4), for use in the method.
    • 在用于检测特定类别的炸药的方法中,可疑样品在液相中连续进行试剂(1),(2),(3)和(4),只有在没有颜色反应 在上述试验中已经获得,而试剂(2)和(3)仅在前一试剂存在下使用。 (1)是可重氮氨基偶氮染料前体(用于硝基芳族炸药)的碱性溶液。 (2)是含有硝酸盐至亚硝酸根离子还原剂和重氮 - 偶合剂(对于有机硝酸盐和硝胺)的强酸性试剂。 (3)是悬浮在包含至少一种水混溶性溶剂(对于无机硝酸盐)的液体中的锌粉。 (4)是均匀强酸性溶液中的苯胺盐,其包括与水可混溶的有机溶剂(对于氯酸盐和溴酸盐)。 本发明还包括用于该方法的测试试剂盒以及试剂(3)和(4)。
