Spectroquant® Prove application fields

Waste water

Regular testing, and the use of cell test kits are common in waste water analysis. Hence, Prove 100 is the perfect choice for these measurements. What’s more, the Spectroquant® portfolio offers the broadest selection of COD tests. Just choose the measuring range that best suits your needs, and ensure precise results.

Waste water

Drinking water and beverages

The analysis of drinking water and beverages typically involves reagent tests since they offer lower detection limits for parameters such as manganese and sulfate. Prove 300 is ideal here as it allows UV/Vis analyses, and is preprogrammed with free applications, like bromate and brewery tests.

Drinking water and beverages

Process water

Even low levels of impurities in process water can lead to damages, downtime, and expensive repairs. To help you avoid these, we have developed the most sensitive silicate and chloride tests with the lowest measuring ranges in the market. For even greater sensitivity, use the 100 mm cell in Prove 600.

Process water
