Low-Volume Aerosol Sampler
Purpose of Participation
- Aerosol sampling for subsequent chemical characterization of aerosol particles by ETV-ICP-MS
- Ground based measurements in connection with airborne activities
Instrument description
Low-Volume Aerosol Sampler with eight stage impactor, cut-off diameter from 0.35-16 µm. Aerosols are deposited and fractioned by an eight stage cascade impactor made by Stroehlein Instruments. It separates particles at a flow rate of 36.7 lmin-1 in eight size classes with cut-off particle diameter corresponds to a 50 % collection efficiency and depends not only on the particle size but also on the density and particle shape.
| Species | Aerosol particles from 0.35-16 µm, Trace elements for different sources |
| Method | |
| Quantity primary | |
| Quantity secondary | |
| Measurement range | |
| Altitude range | |

Specific remarks
- Due to only 6 sampling devices sampling should be carried out for special aerosol conditions (information necessary from LIDAR and sun photometer measurements)
