Abstract:
1. A system for detecting the presence of explosive elements comprising: a testing device having a case with a cover; a sample holder disposed in said case for receipt of a sample element and having a sample retainer; said sample element comprising a swipe pad attached to a backing element wherein said swipe pad is approximately a circular shape, constructed of a woven continuous filament polyester material, is constructed of a roughened material that is resistant to chemical degradation for the entire pH range of approximately 1 to 14, is heat resistant for the entire temperature range of approximately 0 degrees C. to 150 degrees C., and is hydrophilic for each of a first reagent fluid and a second reagent fluid; a heater disposed in said sample holder wherein said heater will be below said swipe pad adjacent said backing element when said sample element is positioned in said sample holder wherein said heater is a variable control heater for the entire temperature range from ambient to approximately 150 degrees C.; said heater in communication with an electric power source; said case having a plurality of cavities formed therein for removable storage of a plurality of fluid containers; and said plurality of fluid containers is two fluid containers wherein a first fluid container has a first reagent fluid of a tetrabutylammonium hydroxide, an ethanol and a water, and a second fluid container has a second reagent fluid of a phosphoric acid, a sulfanilic acid, N-(1-naphthyl) ethylenediamine dihydrochloride and a water.
