Setting or Verifying Flow Rate
When performing multiple-tube sampling using an adjustable
low flow holder (dual, tri, or quad), ensure the regulator has been
activated and the pump flow rate is set at 1.5 L/min. The maximum
flow rate through any one tube is 500 ml/min*. Calculate the sum
of all tube flow rates. If the sum is ≤1000 ml/min, proceed with
calibration and sampling without any further adjustment to the
pump flow rate. If the sum is >1000 ml/min, set the pump flow rate
15% higher than the sum of tube flow rates.
* Back pressure across some sample tubes can be higher than average. In
these instances, the maximum flow rate of 500 ml/min per tube may not be
achieved.
Before use, allow pump to equilibrate after moving it from one
temperature extreme to another.
Ensure pump has run for 5 minutes before proceeding with
calibration.
Ensure the pump is set for low flow. See Activating the Regulator,
page 9.
2
Connect the adjustable low flow holder (Figure 3, page 13)
to the pump intake (Figure 1, #9) using 1/4-inch Tygon tubing.
Insert an opened sorbent tube into each rubber sleeve of the low
flow holder (Figure 3, #3 and 4) with the arrow on the tube pointing
toward the holder.
If sampling with fewer tubes than number of ports, insert
unopened sorbent tubes in the empty ports to seal them.
Connect holder to
pump intake and tube
inlet to calibrator.
Note the flow rates specified by each sampling method and
add them together. If the sum is ≤1000 ml/min, proceed to
the next step. If the sum is >1000 ml/min, multiply the total
tube flow rate by 1.15 and set the pump for that flow rate.
Connect a calibrator to the exposed end of a sorbent tube,
loosen the brass flow adjust screw on the low flow holder, and
activate the pump by pressing Flow and Battery Check.
continued on page 15

Turn the flow adjust screw (Figure 3, #2) for the appropriate
port of the low flow holder until the desired flow rate is
achieved through the tube. Turn clockwise to decrease the
flow.
Do not adjust the flow on the pump. Adjust the flow only by
using the flow adjust screw on the low flow holder.
Do not exceed 500 ml/min flow rate per tube.
