Instrument air: Dry and oil free according to ISA-S7.0.01-1996 quality standard for instrument air
Interferences: Positive interference is caused by Silica Arsenate if the sample is heated. Negative interferences are caused by Arsenate, Fluoride, Thorium, Bismuth, Sulphide, Thiosulphate, Thiocyanate or excess of Molybdate. Blue colour is caused by Ferrous Iron but this does not affect results for Ferrous Iron concentrations < 100 mg/L. If Nitric Acid is used, Chloride interferes from 75 mg/L. Large amounts of colour and turbidity interfere. Fats, oil, proteins, surfactants and tar.
