Nickel Carbonyl 0.1 to 1 ppm

Application Range:

Standard Measuring Range: 0.1 to 1 ppm Discoloration compared to color standard.
Number of Strokes n: 20
Time for Measurement: approx. 5 min
Standard Deviation: ± 50 %
Colour Change: yellow to pink

Ambient Operating Conditions:

Temperature: 0 to 30 °C

Cross Sensitivity:

Iron pentacarbonyl is also indicated by a brownish discoloration, however, with less sensitivity. Measurement of nickel tetra carbonyl is not possible in the presence of hydrogen sulfide of sulfur dioxide, since the reading is suppressed. Such a disturbance can be recognised by decoloration of the indicating layer even before the reagent ampoule is opened..
