Acrylonitrile Detection Tubes 0.5/a (0.5 - 20 ppm)
Draeger Short-term Tubes have proven to be a very cost-effective and reliable method for the measurement of gases.
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, e.g.: Determining and measuring concentration peaks, Measuring personal exposure in the inhalation area, Detecting leaks in pipelines, gas installations etc., and Air analysis in sewers, shafts and confined spaces.
Acrylonitrile Detection Tubes 0.5/a (0.5 - 20 ppm)
| Standard Measuring Range: |
0.2 to 4 ppm / 5 to 50 ppm |
| Number of Strokes (n): |
20 / 5 |
| Time for Measurement: |
approx. 4 min. / approx. 1 min. |
| Standard Deviation: |
�15 to 20 % |
| Color Change: |
yellow -> red |
| Temperature: |
5 to 40� C |
| Absolute Humidity: |
1 to 25 mg H2O / L |
| Reaction Principle: |
a) CH2 = CH-CN + MnO4 ?> HCN
b1) HCN + HgCl2 ?> HCl
b2) HCl + Methyl red ?> red reaction product |
| Cross Sensitivity |
At 4 ppm acrylonitrile there is no effect from:
1,000 ppm acetone,
20 ppm benzene,
1,000 ppm ethyl acetate
In the presence of 500 ppm ethanol, 1000 ppm n-hexane or 100 ppm toluene:
Acrylonitrile is indicated with lower sensitivity and determining the concentration is not possible.
In the presence of 400 ppm butadiene, the indication of 4 ppm acrylonitrile is largely suppressed. |
