Chemo Cobalt Spot Test
The Chemo Cobalt Test is an easy one step method to detect free Cobalt in metallic objects.
The test detects free Cobalt down to a limit of 8.3 ppm (parts/million). The sensitivity threshold of most Cobalt allergic patients is above 10 ppm. Some strongly allergic patients will however still react to objects releasing amounts below the threshold of the test.
Chemo Cobalt Test™ consists of Nitroso-R salt for the detection of Cobalt in various metallic objects. Nitroso R salt produces a bright, redish-pink insoluble salt with Cobalt.
