Battery-operated technical device for qualitative and semi-quantitative nondestructive electrochemical analysis of everyday objects for their nickel content and -laxity by electrography, has power source, particularly nine-volt battery

摘要

The battery-operated technical device is provided with a power source, particularly a 9-volt battery. The 9-volt battery provides power to electric circuits of the battery-operated technical device. The smallest amount of nickel is electrochemically mobilized, where the complex reaction of nickel ions with dimethylglyoxime to bis(2,3-butanedione dioximato) nickel is used to achieve fast and colometrically secure evidence.
