Reagent set for measuring copper in low concentrations. Copper(I) ions form an intense yellow complex with porphyrin, the intensity of which determines the concentration. In natural waters, copper usually only occurs as a trace element in concentrations of up to 20 µg/L. In systems and systems, increased values can be a sign of corrosion of copper lines.
