Interferences in Wastewater Analysis
In photometry, it is important to detect interferences so that measurement results can be evaluated correctly. The composition of the tested samples depends strongly on the upstream processes. When using our test kits, we recommend checking for possible sources of interference in the sample. In this seminar, we will show you which interferences can occur, how to recognize them and how these interferences can be eliminated or avoided. Among other things, we will cover the important industrial parameters COD, Phosphate, Nitrate and Nitrit in theory and practice.
