Low Flow Adaptor for Sampling pumps. Used for the collection of vapour/gaseous phase samples
The sample is normally collected on to an absorbent material (eg Carbon/Tenax etc) in a glass tube. The ends of the sorbent tube are broken off and inserted into a tube holder which is then connected to a personal sampling pump.
Generally the flow is lower (typically 20-200ml/min) and so either a dedicated low flow pump may be used or a medium flow pump, e.g. a Casella Apex2 using this Low Flow Adaptor.
For the sampling of gases and vapours a lower flow rate is generally set (20-200ml/min).
