Abstract The present invention is a vapor phase activator pad for use in a self-contained fingerprinting kit which includes a portable vapor tank into which the vapor phase activator pad is placed in order to fume an object suspected of containing latent fingerprints, the vapor phase activator pad includes a gauze pad. The gauze pad is chemically treated with a composition which consists of specified chlorinated organic solvents so that when a quantity of alkyl-cyanoacrylate is placed onto the vapor phase activator pad, the vapor phase activator pad generates vapors of the chemical cyanoacrylate. The composition consists of a first component and a second component. The first component is a mixture of two selective chemicals, trichloroethane in the range of 1 to 96 percent and stabilized with methanol in the range of 1 to 10 percent. The second component is a mixture of four selective chemicals, nitroethane and nitromethane in the range of 1 to 5 percent and stabilized with toluene in the range of 1 to 4 percent. The second component also includes an activator which is diethylenetriamine in the range of 1 to 9 percent wherein the composition provides a controlled oxidative vaporization of the quantity of alkyl-cyanoacrylate.
A vapor phase activator pad for use in a self-contained fingerprinting kit which includes a portable vapor tank into which said vapor phase activator pad is placed in order to fume an object suspected of containing latent fingerprints, said vapor phase activator pad comprising: a. a gauze pad; b. a composition which consists of specified chlorinated organic solvents wherein said gauze pad is chemically treated with said composition so that when a quantity of alkyl-cyanoacrylate is placed onto said vapor phase activator pad, said vapor phase activator pad generates vapors of the chemical cyanoacrylate.
