The term "water testing" is used to describe diverse procedures to analyze water quality and safety. UV Vis spectroscopy has been used for water testing, and proven to be reliable, fast and easy-to-perform, requiring minimal bench space and able to measure down to low detection limits with sophisticated yet affordable instruments. By this method, a sample of analyte in water can react with given reagents through mixing; after the reaction, the quantity of certain chemicals in the mixture can be determined photometrically with a UV Vis spectrophotometer.
Mettler-Toledo collaborates with Merck to deliver solutions to water analysis in industry segments such as Pharma, Biotechnology, Chemicals, Food & Beverage (F&B), Environmental Testing and Power Generation. The solutions can measure more 180 parameters of substances in waste, process and drinking water for safety and quality control. The photometric water tests are based on both test tubes and cuvettes; however, for high throughput sample demands, water testing workflow can be automated. In addition, the guide illustrates the procedures from water sample preparation to results with predefined water application methods for parameters such as COD, Ammonium, Phosphate, Hardness, Nitrate, Sulfate, etc. There are also options to customize water testing methods to fulfill individual needs.
