6 Set the analyzer gas flow to 100 mL/min.
Figure 3-74
Gas Flow Controls (Shown Before Setting to 100 mL/min.).
CAUTION
Read through steps 7-11 before proceeding. It is extremely important to set the
peristaltic pump drain clamps in a timely fashion after the GLS begins to fill with
liquid. Failing to do so can cause an overflow and spillage.
WARNING
CHEMICAL SPILL HAZARD
Do not start liquid flow without the carrier gas being on and set to 100
mL/min with and pressure set to 120 psi. Otherwise, fluid backfill can
occur.
Refer to the QuickTrace help or software manual for more information on
instrument control.
7 Place the autosampler sample probe into rinse station. Click the Up button,
then the Park button. Visually verify the probe's movement.

8 Place a Kimwipes ® wiper at the GLS gas exit port to prevent any liquid from
spilling onto the GLS mount.
9 Manually increase the clamp tension on the Santoprene ® sample tubing
(Channel three) until liquid uptake begins to flow with a jerky motion in the
sample tube from the autosampler. Now rotate the tension screw ¼ turn past
this point and verify that the flow is steady.
