Description

General description

Method: reflectometric with test strips and reagents 2.5 - 45.0 mg/l Ca Reflectoquant^®

The Reflectoquant Calcium test includes test strips and all necessary additional reagents and is suitable for rapid determination of calcium in aqueous media. Calcium is an important parameter for boiling and cooling water. If the water contains calcium, deposits can be found in the plants and this can influence the function of the machines. Calcium also needs to be analyzed in drinking water and especially in beer. In the presence of hydrogen peroxide calcium ions react with glyoxal-bis(2-hydroxyanil) to form a red complex that is determined reflectometrically on the RQflex. For pre-testing a sample in an economic and quick way to estimate the calcium concentration and a possible dilution factor prior to using this quantitative method we recommend our semi-quantitative MQuant test strips for calcium. Further quantitative determination methods can be found with our Spectroquant tests.
