Drager NIOSH Pattern Activated Charcoal Tube

Drager NIOSH Pattern Activated Charcoal Tube: length - 70mm, diameter - 6mm, contents - 100 mg and 50 mg charcoal

Advice for sample-taking

The air to be analysed must be drawn through the tube at a constant flow rate between 0.01 and 0.2 L/min. During sampling the activated charcoal tube should be in a vertical position. This guarantees a constant flow of air through the activated charcoal.  NIOSH points out in its regulations that the absorption capacity of activated charcoal is affected by high air humidity, which may result in pre -mature breakthrough of the substance to be measured into the control layer. A special tube adapter (order no. 6728639) is necessary in order to use Drager pumps for sampling. After sampling the tube should be sealed with the polyethylene supplied caps.  

Note concerning the analysis 

The enriched volatile organic compounds are analysed in accordance with the procedures recommended by BGIA, DFG, NIOSH, OSHA and HSE.
