Product description
Drager Nitrous Oxide Sampler
Please note: this product is now obsolete.
Drager Nitrous Oxide Sampler: Passive Sampling Tubes - Nitrous Oxide Sampler, packet of 10 including 2 holders.
NOTE: This product has a shelf life of 2 years.
Advice for sample-taking
The sampling time of nitrous-oxide diffusion sampler depends on the expected oxide nitrous concentration in the air to be analysed. The following sampling times are recommended in the case of measurements in the range of 5 to 100 mL/m3 (ppm) nitrous oxide:
| Nitrous Oxide Concentration | Recommended Sampling Time |
| 5 ppm | 4 to 8 h |
| 25 ppm | 1 to 8 h |
| 50 ppm |
30 min to 8 h |
| 100 ppm | 15 min to 8 h |
After sampling the tube must be sealed with the polyethylene supplied caps.
Note concerning the analysis
The analysis is made according to DFG method No. 2"Dinitrogen monoxide" via thermodesorption and infrared spectroscopy.
