The purpose of the Conference, this time to study performance.
Phantom fingers on the paper by comparison between the use of solution 1, 2-indanedione. Ninhydrin solution Aqueous solution of DFO and with iodine found how to use solution 1, 2-indanedione validate performance fingerprint alias on paper better than the method using ninhydrin and DFO solution solution, but with lower efficiency of iodine in aqueous solution, but DFO finger longer treatment. When comparing the efficiency of the fingerprint verification with shining fluoret Zen. It was found that compounds 1, 2-indanedione. To glow, and then see the finger above the ninhydrin solution treatment with zinc or cadmium metal and soluble compounds DFO.
