| Acrolein | 0.1 to 10 ppm | ||
| Dimethyl Sulphide | 1 to 60 ppm |
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 % |
| Colour Change: | violet to yellow brown |
Ambient Operating Conditions:

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..
