Monitoring organic chemicals in the air – whether they arise from anthropogenic or natural sources – is vital for assessing everything from their impact on human health to their role in global climate.
In this Applications Guide, we describe how thermal desorption (TD) can be used to monitor compounds in a wide range of scenarios across the field of environmental monitoring.
The main sampling techniques covered include:
- Passive (diffusive) sampling of air on to sorbent tubes
- Pumped (active) sampling of air on to sorbent tubes
- On-line monitoring of air/gas streams
- Pre-concentration of air samples collected in canisters.
