Chemo Nickel Spot Test

The Chemo Nickel Test™ is an easy one step method to detect free Nickel in metallic objects.

The test consists of an ammoniacal solution of Dimethylglyoxime (DMG) for the detection of nickel in various metallic objects. DMG produces a bright, reddish-pink insoluble salt with nickel. The Spot test detects free nickel down to a limit of 10 ppm (parts/million)1. The sensitivity threshold of most nickel allergic patients is above 11 ppm. Some strongly allergic patients will however still react to objects releasing amounts below the threshold of the test.
