1. A thin-layer chromatography method for detection and identification of explosives in samples, comprising the steps of:

  • provide a reverse-phase thin-layer chromatography plate, prepare said plate by marking spots on which to deposit the samples;

    spot one micro liter of a first standard onto one of said spots, spot one micro liter of a second standard onto another of said spots, and spot samples onto other of said spots producing a spotted plate;

    add eluent to a developing chamber;

    add said spotted plate to said developing chamber;

    remove said spotted plate from said developing chamber producing a developed plate;

    place said developed plate in an ultraviolet light box;

    add a visualization agent to a dip tank;

    dip said developed plate in said dip tank and remove said developed plate; and

    detect explosives by viewing said developed plate.
