Abstract:
1. A test kit for the detection of nitrogen containing particulates consistent with explosive mixtures comprising: a tubular sleeve formed transparent thermoplastic flexible material, said sleeve being transversely sealed at one end and having a reverse fold at the other end to form a sealed thin walled generally rectangular cavity in said sleeve; a generally rectangular planar test strip including a base layer having an adhesive layer one surface, said test strip including a peelable layer overlying said adhesive layer, said peelable layer having a transverse score line separating said peelable layer into a first panel and a second panel, said second panel being removable to permit application of said adhesive layer against surfaces suspected of having said particles of nitrogen containing compounds thereon; an opaque substrate disposed opposite said test strip in assembly, said opaque substrate having a coloration providing clear contrast to bluish coloration, a crushable elongate glass ampoule in said cavity containing a reagent solution of diphenylamine of sulfuric acid; and a U-shaped clip having spaced resilient legs engaging said folded end whereby crushing said ampoule in said cavity will release said reagent solution onto said test strip and cause a blue coloration to any of said particles on said adhesive layer after removal of said second panel, said blue coloration being clearly visible through said sleeve against said opaque substrate.
