- analysis of the sample in a laboratory
- measurement of complex compounds and mixtures of substances possible
- detection of low concentrations possible
The hazardous substances in the air are collected using a suitable medium – such as activated charcoal, silica gel or molecular sieves. The sample is then analyzed in a laboratory with the aid of instrumental analysis. The sampling process is conducted either actively with a manual Dräger accuro or automatic Dräger-Tube pump X-act 5000, or passively via a diffusion sampler.
