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 spot concentrations of specific gases. Measurement usually takes between 4 seconds and 15 minutes. The tubes are used either manually with the Draeger-Tube Accuro Pump or automatically with the Draeger X-act 5000.
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
Nickel Tetracarbonyl Detection Tubes 0.1/a (0.1 - 1 ppm)
| 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. |
