Draeger 8103701 Acrylonitrile 0.2/a Detector Tubes (10 tests per box)

Application Range:

• Standard Measuring Range: 0.2 to 4 ppm / 5 to 50 ppm
• Number of Strokes n: 20 / 5
• Time for Measurement: Approx. 4 min / 1 min
• Standard Deviation: ± 15 to 20 %
• Color Change: Yellow → Red

Ambient Operating Conditions:

• 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 no effect from:
  • 1000 ppm acetone, 20 ppm benzene, 1000 ppm, ethal 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 concetration is not possible.
  • In the presence of 400 ppm butadiene, the indication of 4 ppm acrylonitrile is largely suppressed.
