Persistant Interferences
1. All oxidising agents in the samples react like chlorine, which leads to higher results.
2. Concentrations above 6 mg/l Ozone can lead to results within the measuring
range of up to 0 mg/l. In this case, the water sample must be diluted. 10 ml of the
diluted sample should be mixed with the reagent and the measurement taken again
(plausibility test).
