The method is used to store impurities on platelets that are basic and hygroscopic (moist). Acidic gaseous air pollutants that overcome the diffusion resistance to the platelet are captured. Subsequent centralized analysis is possible.
The sampling device consists of:
- filter holder ring,
- 4 assembly trains,
- Empty filter,
- standpipe,
- Threaded cap.
The main features of the SAM measuring device are:
- Low maintenance
- Determination of the dust content of precipitation (moisture disposition)
- good value for money
- quantitative collection
- Rilasan coating to prevent heavy metal contamination
