Dimethyl Sulfide Detection Tubes 1/a (1 - 15 ppm)
For short-term measurements more than 160 Draeger Tubes are available to measure the so called spot concentrations of specific gases.
A wide range of different gases and vapours can be detected and measured, such as:
- Determining and measuring concentration peaks
- Measuring personal exposure in the inhalation area
- Detecting leaks in pipelines, gas installations etc.
- Air analysis in sewers, shafts and confined spaces
|Standard Measuring Range:
||1 to 15 ppm
|Number of Strokes (n):
|Time for Measurement:
||approx. 15 min
||±15 to 30%
||violet ─> yellow brown
||15 to 30° C
||< 20 mg H2O / L
||(CH3) 2S + KMnO4 ──> MNIV + various oxidation products
||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.
