Arsine Detection Tubes (0.04 to 10 ppm)

This detector tube measures Arsine

  • Measuring Range:
    • 0.04 to 0.1 ppm - 10 pump strokes
    • 0.1 to 1.5 ppm - 5 pump strokes
    • 1.5 to 2.4 ppm - 3 pump strokes
    • 2.4 to 10 ppm - 1 pump stroke
  • Sampling Time: 1.5 minutes per pump stroke
  • Detecting Limit: 0.02 ppm (n=10)
  • Changes from Yellow to Red
  • 2 Year Shelf Life
  • TLV-TWA, C (ACGIH) (ppm): .005
  • Reaction Principle:
    • Arsine react with mercuric chloride to produce hydrogen chloride. The indicator of the tube turns to red. AsH3 + 3HgCl2 → As(HgCl)3 + 3HCl HCl + Basic compound → chloride compounds
  • Coefficiant of Variation:
    • 10% (for 0.1 to 0.5 ppm), 5% (for 0.5 to 1.5 ppm)
  • Store the tubes at a cool and dark place.
  • Comes in a Box of 10
