Dimethyl Sulfide 1/a, 1 - 15 PPM, Part # 6728451, 5 Tests 

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 š yellow brown

Ambient Operating Conditions

Temperature: 15 to 30 °C

Absolute Humidity: < 20 mg H2O / L

Reaction Principle

(CH3) 2S + KMnO4 š 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
