Gas & Vapour Sampling using Sorbent Tubes
You will need :-
• Sidekick sample pump (fully charged)
• Constant pressure controller (CPC)
• Low flow adaptor (tube holder)
• Tube cover of appropriate size for the sorbent tube
being used
• A length of flexible tubing
• Tube adaptor for small diameter sorbent tubes (SKC
part no. 717-511)
• Two sorbent tubes from the same box or batch
• Flow calibration device capable of measuring the
intended flow rate, typically between 5 and 500 ml/
min, such as the Defender primary calibrator
• Toolkit to adjust the flow rate
1. Connect the flow calibrator directly to the sample
pump inlet hosetail using the length of tubing. Turn on
the pump and adjust the flow rate to 1.5 litre/minute.
This is the required flow rate for correct operation
of the constant pressure controller (CPC). Switch
off the pump and disconnect the flow calibrator.
No further adjustment of the pump flow rate
should be made.
2. Connect the CPC unit to the pump. The
short length of tube already attached to the
CPC is connected to the pump inlet hosetail.
This now puts the pump into the low flow
mode and allows use of the low flow adaptor.

The combined low flow adaptor and tube holder

using the length of tubing. As a further check that
the connections are correct, the labelled side of
