7.3 Tubing Connections
The required tubing connections are between the two supply bottles and the peristaltic
pump, the liquid sample PEEK tube from the PILS droplet impactor and the peristaltic
pump, the peristaltic pump and the drain bottle, the rear panel vacuum fitting and the
vacuum pump, and between the user sampling inlet and the air sample flow inlet of the
PILS.
Peristaltic Pump
Fill the liquid supply bottles with high-quality, 18 mega-ohm water. The bottle labelled
'Pure H2O+LiF' feeds the peristaltic pump channel that supplies washflow to the PILS
impactor with pure water spiked with internal standard (LiBr or LiF, 50 to 200 ppb). The
bottle labelled 'Pure H2O' should be filled with pure water only for the steam generator.
Follow the labels on the peristaltic pump tubing to properly connect the bottles to the
pump.
Connect the liquid sample PEEK tubing supplied with the PILS to the liquid sample tub-
ing in the peristaltic pump channel by sliding the PEEK tubing into the pump tubing with
a minimum 1/4" engagement. The pump tube should be labelled. Connect the other end
of the PEEK tubing to a BRECHTEL Auto-collector to fill vials or to your analytical device
so liquid samples may be analyzed. Alternatively, allow the liquid sample out to drip into
a beaker and manually fill vials when desired for batch sample collection.
Verify that the peristaltic tubing installed in the pump to supply the impactor liquid
washflow and the liquid sample outlet flow will provide an appropriate liquid flow rate
