Sampling media
TERA Environnement provides you with all the equipment you need for your air measurement campaigns!
When taking air samples, you can opt for either passive or active samplers. The choice of sampler takes into account, among other things, the medium being sampled, the substances being sought and the specific constraints of the measurement project.
Each sampling method has its advantages and disadvantages:
| Passive samplers | Active samplers | |
|---|---|---|
| Implementation | Simple to use and lightweight device | Use with a sampling pump |
| Sampling location | Recommended for : Indoor air Ambient air Workplace air | All air matrices including : Soil gases Emission air Workplace air |
| Sampling time | from 8 hours to several days | from a few hours to 8 hours |
| Range of compounds | Typical air quality compounds | Very wide range of compounds |
| Cost | Economical | More expensive than passive samplers, but offers performance for certain compounds that passive samplers cannot. |
