Ethylene Glycol Detection Tubes (10 - 180 mg/m3)
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 vapors 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 Glycol Detection Tubes (10 - 180 mg/m3)
| Standard Measuring Range: |
10 to 180 mg/m3
Corresponds to 4 to 70 ppm |
| Number of Strokes (n): |
10 |
| Time for Measurement: |
approx. 7 min |
| Standard Deviation: |
±20 to 30 % |
| Color Change |
white ─> pink |
| Temperature: |
10 to 35° C |
| Absolute Humidity: |
4 to 15 mg H2O / L |
| Reaction Principle: |
a) OH-C2H4-OH ──> 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 glycol in the presence of formal dehyde and ethylene oxide because they produce the same discoloration. |
| Additional Information: |
The reagent ampoule must be broken before carrying out the measurement. |
