    Chromium Analyzer Heinrich Proch Overview

    The Chromium Analyzer Heinrich Proch can perform continuous analysis of metals, such as Chromium (Cr), 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 Chromium Analyzer guarantees 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.

    Sources

    Natural sources. Chromium is widely distributed in the Earth’s crust. It can exist in valences of +2 to +6. In general, food appears to be the major source of intake.
    Industry. Chromium is seldom used alone; as an additive, it endows alloys or materials with new properties: strength, hardness, permanence, hygiene, color, and resistance to temperature, wear, and corrosion.
    Drinking water. A guideline value of 0.05 mg/liter of total chromium is recommended in drinking water.
    Toxicity. In humans and animals, Cr(III) is an essential nutrient. The overall toxicity, carcinogenicity, and general hazards of chromium are highly related to chemical speciation, the hexavalent chromium compounds being more toxic than the trivalent compounds.

    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 the cuvette containing formed metal complex is directly proportional to metal concentration.
