Draeger 6728451 Dimethyl Sulfide 1/a Detector Tubes (5 tests per box)

Application Range:

• Standard Measuring Range: 1 to 15 ppm
• Number of Strokes n: 20
• Time for Measurement: Approx. 15 min
• Standard Deviation: ± 15 to 30 %
• Color Change: Violet → Yellow Brown

Ambient Operating Conditions:

• Temperature: 15 to 30 °C
• Absolute Humidity: < 20 mg H2O / L

Reaction Principle:

• (CH3) 2S + KMnO4 → MnIV + various oxidation products

Cross Sensitivity:

• Many organic compounds with C=C double bonds are indicated as well, but with different sensitivities.
• It is impossible to differentiate between them.
• H2S (hydrogen sulfide) is indicated with approximately twice the sensitivity.
• The tube H2S 5/b can be used as a filtering tube.
• Then, with n = 20 pump strokes approx. 30 ppm H2S is retained.
• Methyl mercaptan is indicated with approximately twice the sensitivity.
