Use only the purple-black tubing for draining the ICP/VGA 77 system. Other
NOTE
smaller diameter pump tubing, for example the black-black tubing, may not give a
large enough drain flow rate. The instrument peristaltic pump rate must be
sufficient to remove all waste liquid from the gas/liquid separator (typically
40–45 rpm).

Fit a purple-black pump tube to the instrument peristaltic pump
as described in your instrument operation manual.
Connect the inlet of the purple-black pump tube to the drain
outlet of the gas/liquid separator in the ICP reagent module.
(Refer to Page 41 for a diagram of the ICP plasma gas/liquid
separator.)
Attach a suitable length of the PVC tubing supplied to the outlet
of the purple-black pump tube from the ICP instrument.
Place the free end of the PVC tubing into the waste container.
Ensure that the tubing is free of kinks or sharp bends so that the
waste liquid will drain freely into the waste vessel.
Open the pressure bar to release the front and rear tube beds.
Swing both tube beds clear of the pump rollers.
Fit black-black tubing into the two innermost tubing slots and
purple-black tubing to the outer most tubing.
Connect the inlet end of the innermost tube to the black rubber
connector at the top of the reagent manifold marked 'Red. ->'.
Connect the other end to the black rubber connector near the
middle of the reagent manifold marked 'Reductant <-'.
