Dräger Sampling Tubes and Systems - Draeger

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. Suitable for ...

Validating Air Sampling Methods | Bureau Veritas

Bureau Veritas was successful in validating an air sampling and analysis method for the client's compound of interest over a range of 0.1x to 2x the OEL. The chemical/physical properties of the analyte required sampling using both a filter and sorbent material. A custom OVS tube was necessary in order to achieve acceptable retention, recovery, and stability performance on both the filter and ...

Sampling and Analysis of Gases and Vapours [Air .

For air sampling at which the enrichment of substances is neither possible, nor necessary, gas storage vessels (e. g., gas mouse) or gas sample bags (e. g. Tedlar™‐bags) can be used. Gas storage bags are available in different sizes. Sampling thereby requires that the bags are connected to a pump and that the air sample is drawn with a flow rate of 1–3 L/min. It is suggested that the air ...
