Dimethyl Sulfate Detection Tubes 0.005/c (0.005 - 0.05 ppm)
For short-term measurements more than 160 Draeger-Tubes are available to measure the spot concentrations of specific gases. Measurement usually takes between 4 seconds and 15 minutes. The tubes are used either manually with the Draeger-Tube Accuro Pump or automatically with the Draeger X-act 5000.
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
Dimethyl Sulfate Detection Tubes 0.005/c (0.005 - 0.05 ppm)
| Standard Measuring Range: |
0.005 to 0.05 ppm
Discoloration compared to color standard. |
| Number of Strokes (n): |
200 |
| Time for Measurement: |
approx. 50 min |
| Standard Deviation: |
±30 % |
| Color Change: |
white ?> blue |
| Temperature: |
15 to 30° C |
| Absolute Humidity: |
3 to 15 mg H2O / L |
| Reaction Principle: |
Dimethyl sulphate + 4-(4-Nitrobenzyl)-pyridine
??> colorless alkylation product
colorless alkylation product ??> blue reaction product |
| Cross Sensitivity: |
Phosgene and chloroformates cause a yellow discoloration of the indicating layer, and it is impossible to perform a dimethyl sulphate measurement. Alcohols, ketones, aromatics and petroleum hydrocarbons in the TLV range do not affect the indication. |
| Additional Information: |
After carrying out the required 200 pump strokes the reagent ampoule must be broken, the liquid transferred onto the indicating layer and carefully drawn through it using the pump. Wait five minutes before evaluating the indication. The tube must not be exposed to direct sunlight during the 5 minute waiting period. |
