Instrument air: Dry and oil free according to ISA-S7.0.01-1996 quality standard for instrument air
Interferenser: Chloride > 1 g/L, inorganic reducing agents such as nitrites, sulphides and iron(II) will increase the result, aromatic hydrocarbons and pyridine are not oxidized to any appreciable extent. Some very volatile organic substances may escape the oxidation by evaporation. Straight chain aliphatic compounds are effectively oxidised by the silver sulphate/sulphuric acid solution. Fats, oil, proteins, surfactants and tar.
Kalibrering: Automatic, 2-point; frequency freely programmable
Kuvetter: 40 minutes, including oxidation time of 30 minutes.
Remark: standard method for Cr destruction requires 120 minutes.
Målemetode: Redox titration after oxidation by acid-potassium dichromate solution, conform with ISO 6060 method Or redox titration after oxidation by potassium permanganate solution, conform with ISO 8467 and JIS K0806 methods
