• ​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 carbon, silica gel, or molecular sieves. The sample is then analyzed in a laboratory with the aid of instrumental analysis.

Dräger sampling tubes and systems allow identification and measurement of different substances even under difficult conditions. Very complex mixtures of substances or cases in which several similar substances are present at the same time can be measured accurately with Dräger Tubes.
