To demonstrate a positive test, test a nickel coin. It contains 25% nickel and will turn the swab pink indicating nickel is detected. Nickel Alert can be used to retest items coated with Nickel Guard ™ to verify protective barrier is in place. Nickel Alert should be used in well-ventilated areas.

- Dec 01, 1977 The dimethylglyoxime test for detection of nickel, first described by Fleigl 1 and modified by Fisher, 2 consists of adding a few drops of 1% dimethylglyoxime in alcoholic solution and a few drops of 10% ammonium hydroxide solution to a test object and observing for the presence of a red precipitate. In our modification of this procedure, a few.
dimethylglyoxime
[‚dī¦meth·əl·glī′äk‚sīm]
(organic chemistry) 
(CH3)2C2(NOH)2 White, crystalline or powdered solid, used in analytical chemistry as a reagent for nickel.
Dimethylglyoxime
diacetyl dioxime:
Colorless crystals; melting point, 238°-240°C. It is soluble in alcohol, ether, and solutions of alkalies. With nickel salts it yields a red insoluble precipitate of nickel dimethylglyoximate, (C4H7O2N)2Ni, which is a chelate compound. Because of this, dimethylglyoxime is used for the qualitative and quantitative determination of nickel. In 1905, L. A. Chugaev suggested the use of dimethylglyoxime as a specific reagent for nickel. Dimethylglyoxime is made by treating diacetyl with hydroxylamine.
