A review of sorbent-based sampling methods for volatile and semi-volatile organic compounds in air

Application Note 027

Sorbent tubes/traps are widely used in combination with gas chromatographic (GC) analytical methods to monitor the vapour-phase fraction of organic compounds in air.

This application note reviews the key features and limitations of the main air sampling options and gives guidance on the appropriate application scope of each.

The sampling options discussed are:

  • Sorbent-based air sampling
  • Diffusive (passive) sampling
  • Whole-air sampling
