Interferences:
Strong reducing agents like Hydrosulphide, Nitrite > 0,2 mg/L, Sulphite > 200 mg/L and Thiosulphate > 5 mg/L interfere by reducing the blue colour. Oxygen reacts with Sulphide and must be avoided. Large amounts of colour and turbidity interfere. Fats, oil, proteins, surfactants and tar.
