Advice for sample-taking

This construction is developed, for a high adsorption capacity of the sampling layer.This tube is typically sufficient for sampling in the range of limit value measurements. If higher concentrations of harmful substances are expected, the sampling tube must be inserted with the air flow opposite to the flow indicating arrow (long layer in front; note in the sampling record!). After sampling the tube should be sealed with the polyethylene supplied caps.
