Iron Analyzer – Joseph von Eybler Overview

The Iron Analyzer – Joseph von Eybler can perform continuous analysis of heavy metals, such as Iron (Fe), 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 Iron Analyzer Joseph von Eybler 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.

Natural sources. Iron is one of the most abundant metals in the Earth’s crust. It is found in natural freshwaters at levels ranging from 0.5 to 50 mg/liter. Industry. Iron is used for various alloys, steel, in the galvanization process and other industrial processes.
Drinking water. Iron may be present in drinking water as a result of the use of iron coagulants or the corrosion of steel and cast iron pipes during water distribution. There is usually no noticeable taste at iron concentrations below 0.3 mg/liter, and concentrations of 1–3 mg/liter can be acceptable for people drinking anaerobic well water.
Toxicity. Iron is an essential element in human nutrition. Estimates of the minimum daily requirement for iron depend on age, sex, physiological status, and iron bioavailability and range from about 10 to 50mg/day. Portable water should contain iron, not more than 0.2 mg/L. Groundwater may contain iron at concentrations of several milligrams per liter.

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.
