Standard Measuring Range : 0.1 to 1 ppm
Discoloration compared tocolour standard.
Number of Strokes (n) : 20
Time for Measurement : app. 5 min
Standard Deviation : ± 50 %
Colour Change : yellow -> pink
Ambient Operating Conditions
Temperature : 0 to 30 °C
Absolute Humidity : < 30 mg H2O / L
Reaction Principle
a) Ni(CO)4 + I2 -> NiI2 + 4 CO
b) NiI2 + Dimethylglyoxime -> pink coloured complex
Cross Sensitivity
Iron pentacarbonyl is indicated with a brown discoloration and witha lower sensitivity than nickel tetracarbonyl.Hydrogen sulphide and sulphur dioxide react with the iodine preparationand can suppress the nickel tetracarbonyl indication. TheInstructions for Use of this tube describe how the interference canbe quickly recognized.
Additional Information
After performing the required 20 pump strokes the reagent ampoulemust be broken and the liquid carefully drawn onto the indicationlayer using the pump.
