Nickel Tetracarbonyl Detection Tubes 0.1/a (0.1 - 1 ppm)

For short-term measurements more than 160 Draeger Tubes are available to measure the so called spot concentrations of specific gases.

A wide range of different gases and vapours can be detected and measured, such as:

  • Determining and measuring concentration peaks
  • Measuring personal exposure in the inhalation area
  • Detecting leaks in pipelines, gas installations etc.
  • Air analysis in sewers, shafts and confined spaces
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 %
Color Change: yellow ──> pink
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 colored complex
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.
Additional Information: After performing the required 20 pump strokes the reagent ampoule must be broken and the liquid carefully drawn onto the indicating layer using the pump.
