The SEIBOLD COMPOSER Analyser can perform continuous analysis of heavy metals in water. The colorimetric analysis – stated by the WHO as reliable and most suitable method for online analysis – is used for reliable and accurate results and low total cost of measurement (TCM).
The measurement principle is Spectrophotometric, based on Lambert- Beer’s law. Metal is measured as a chelate complex between metal ions in the sample water and sensitive spectrophotometric reagent dye. The change of intensity of the visible light transmitted through the cuvette containing the formed metal complex is directly proportional to metal concentration.
