Sampling

Air Sampling - Lung method, bags

Lung principle

The gas of interest is captured in a gas sampling bag. In order to avoid moisture in the sampling bag, a pre-dilution can be performed.

Air Sampling - Canisters

Canisters

These metal containers are set to vacuum at the lab and can be used for grab sampling in situ.

Air Sampling - Adsorption Tubes, Active and Passive

Adsorption tubes

The gas is directly sampled onto the adsorbent. 

Gas washing

The gas is sent through an absorption liquid, which captures the compounds. Afterwards, the liquid is analysed for specific compounds.
