Figure 1: GD Profiler 2 GDOES Sofia Gaiaschi, HORIBA Scientific, 16 rue du Canal, 91160 Longjumeau, France Introduction Even if alchemy does not exist, electroplating can be considered the next best thing. The idea is to coat relatively common metals (e.g. copper, steel, etc.) with a more precious one (e.g. gold, silver, etc) using electricity! Actually electroplating has many different uses, besides making cheap metals look expensive. Indeed, it can be used to make anti-corrosion coatings, to produce a variety of alloys like brass or bronze on steel, etc... In order to optimize the manufacturing process, it is of great importance not only to determine the thickness/composition of the electroplated coating, but also to verify the absence of contaminants in the electrolytic baths.
