Claim:
1. A test for determining the presence of explosives residue on a suspect surface, comprising the steps of: providing an explosives tester having a tester body, a removable sample pad, and a breakable or squeezable ampoule containing an explosives detecting reagent; removing said removable sample pad from said tester body; swiping said removable sample pad on the suspect surface to collect said explosives residue; positioning said removable sample pad with said explosives residue in said tester body proximate said breakable or squeezable ampoule containing said explosives detecting reagent; squeezing or breaking said breakable or squeezable ampoule containing said explosives detecting reagent dispensing said explosives detecting reagent onto said removable sample pad with said explosives residue producing a color reaction with said explosives residue and a color on said removable sample pad; providing a cell phone having a camera feature, different color channels, storage capability, time determination capability, and a global positioning system capability; taking a picture of said removable sample pad with said color on said removable sample pad with said cell phone having said camera feature, different color channels, storage capability, time determination capability, and a global positioning system capability thereby capturing an image of said color; and using said cell phone having said camera feature, different color channels, storage capability, time determination capability, and a global positioning system capability for processing said image of said removable sample pad with said color on said removable sample pad to determine whether said color reaction indicates the presence of explosives residue on the suspect surface; wherein said cell phone having said camera feature, different color channels, storage capability, time determination capability, and a global positioning system capability for processing said image of said removable sample pad with said color on said removable sample pad includes a standard from different colorimetric tests; using said standard from different colorimetric tests to compare said color reaction with said standard to provide confirmation of the presence of explosives residue on the suspect surface, and storing said image and time of said sample pad with said color using said cell phone having said camera feature, different color channels, storage capability, time determination capability, time determination capability, and a global positioning system capability thereby providing documentation of the presence of explosives residue on the suspect surface.
