Cuprotesmo allows the quick and easy detection of copper(I) and copper(II) ions. It is used for the detection of copper and copper salts on surfaces and in ash, for the detection of pores in metallic coatings on copper containing materials, in criminal trace investigations (bullets), and for the detection of copper-containing pesticides on fruit and vegetables.
