Carbon Disulfide 0.63-100 ppm Detection Tubes

Gastec Detection Tube No. 13 measures Carbon Disulfide with a Range of 0.63 to 100 ppm.

  • Measuring Range:
    • 0.63 to 1.25 ppm
    • 1.25 to 2.5 ppm
    • (2.5) to 50 ppm
    • 50 to 100 ppm
  • No. of Pump Strokes: 4, 2, 1, 1/2
  • Correction Factor: 1/4, 1/2, 1, 2
  • Sampling Time: 12 min, 6 min, 3 min, 1.5 min
  • Detecting Limit: 0.3 ppm (4 pump strokes)
  • Color Change: Blue to Yellow
  • Correction for Temperature & Humidity: Temperature correction is necessary
  • Relative standard deviation: 10 % (for 2.5 to 10 ppm), 5 % (for 10 to 50 ppm)
  • Shelf Life: 3 years
  • Reaction Principle:
    • CS2 + CrO3 + H2S2O7 → SO2 + CO2
    • SO2 + BaCl2 + H2O → BaSO3 + 2HCl
    • HCl + Base → Chloride

Possible coexisting substances and their interferences:

Substance Concentration Interference Changes color by itself to
Sulfur dioxide ≧ 1/5 + Yellow
Ammonia No No
Hydrogen cyanide ≦ 200 ppm No No
Hydrogen sulfide is trapped in the pretreatment layer.
