Arsenic Analyzer Wilhelm Kienzl Overview

The Arsenic Analyser Wilhelm Kienzl can perform continuous analysis of metals, such as Arsenic (As), 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 Arsenic Analyzer guarantee a long lifetime and minimum maintenance efforts. Low consumption of reagents and very high reagent stability ensures people free operation. Automated calibration and cleaning steps support this goal.

Arsenic is found in the atmosphere, in water, soils, sediments, and organisms due to releasing by various industrial processes, mining or smelting, and agricultural activities as well as a by-product of coal combustion.
Natural sources. Arsenic is found in more than 245 minerals.
Anthropogenic sources. The main sources of arsenic are copper and lead ores.
Industry. Arsenic is used as an additive in special alloys, in the microelectronics and the semiconductor industry, as a decolorizing agent in the glass and ceramics industries.
Arsenic in water. Arsenic is found in groundwater as a result of the strong influence of water-rock interactions. Usual groundwater concentrations range from 0.5 to 10 µg/L.
Drinking water. The current WHO provisional level of As in drinking water for the European Union is 10 µg/L, and the current level in the United States is 50 µg/L.

Method: 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.
