Copper Analyzer Johann H. Schmelzer Overview

The Copper Analyzer Johann H. Schmelzer can perform continuous analysis of metals, such as Copper (Cu), and many other parameters in water. Technologies employed are colorimetric (photometric) and ion-selective electrodes (ISE). Direct measurements, standard addition, and titration support the ideal measurement strategy. The robust design and high-quality parts of the Copper Analyzer Johann H. Schmelzer guarantee a long lifetime and minimum maintenance efforts. Low consumption of reagents and very high reagent stability ensures person-free operation. Automated calibration and cleaning steps support this goal.

Copper is both an essential nutrient and a drinking-water contaminant
Natural sources. Most of the world’s Cu is found and mined in the form of copper sulfides and in combination with other metals that can also form multi-metal- sulfide minerals (Fe, Sn, Pb, Se, As, Sb and Ag).
Industry. Copper is used for in gelectroplating and semiconducting industry,…
Natural water. Copper is found in natural surface waters at an average concentration of 0.002 mg/L, ranging from 0.001 to 0.1 mg/L, Cu in seawater is at the upper end of the range.
Drinking water. Copper concentrations in drinking water vary widely, with the primary source most often being the corrosion of interior copper plumbing. A guideline value of 1.5 mg/liter was recommended for copper in drinking- water.
Toxicity. Copper is not very toxic to animals and humans but can be toxic to some fish, many invertebrates and microbes, particularly fungi, algae, and bacteria.

Metal is measured as a chelate complex between metal ions in the wastewater and sensitive spectrophotometric reagent dye. Change of the intensity of the visible light throughout cuvette containing formed metal complex is directly proportional to metal concentration.
