Ethylene Oxide Detection Tubes 1/a (1 -30 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.
Ethylene Oxide Detection Tubes 1/a (1 -30 ppm)
| Standard Measuring Range: |
1 to 15 ppm |
| Number of Strokes (n): |
20 |
| Time for Measurement: |
approx. 8 min |
| Standard Deviation: |
±20 to 30 % |
| Color Change: |
white ?> pink |
| Temperature: |
10 to 30° C |
| Absolute Humidity: |
3 to 15 mg H2O / L |
| Reaction Principle: |
a) Ethylene Oxide ??> HCHO
b) HCHO + C6H4(CH3)2 + H2SO4 ??>
quinoid reaction products |
| Cross Sensitivity: |
Styrene, vinyl acetate and acetaldehyde are indicated with a yellowish brown discoloration.
It is impossible to measure ethylene oxide in the presence of ethylene glycol and formaldehyde because they produce the same discoloration. |
| Additional Information: |
The reagent ampoule must be broken before carrying out the measurement. |
