Water Transfer Line Installation
The Archon transfers, cleans and dilutes liquid samples to the sparge tube via a
five-foot stainless steel line and attaches to the 2-way valve on the top of the
sparge tube. Refer to Figure 2-13.
1. Locate the nut and ferrule and the line from the accessory kit.
2. Uncoil the line. Locate the tan-colored PEEK valve body manifold inside the
right rear of the Archon. Slide the line into the fitting on the left. Tighten the
fitting by hand.
3. Route the line through the “notch” in the rear panel of the Archon labeled
“Waste Lines.” Route the line to the purge and trap.
4. The line will attach to the black 2-way valve on the top of the sparge tube.
5. Turn the handle so the valve is open toward the Archon transfer line. Look in
the port to ensure the holes are aligned.
6. Slide the nut and reverse ferrule over the line and insert into the port on the
left side of the toggle valve. Tighten the nut.
7. Replace the rear door panel.
8. Remove sparge vessel. Make a slight bend about 3” (7.5 cm) of needle. (This
maximizes the rinse ability of the Archon.)
Tekmar 2000 Setup Specifications
After the Archon is installed, the Tekmar 2000 MUST be properly configured to
allow the I/O switch closures and method parameters to function correctly. These
settings will cause the Archon and the purge and trap to properly communicate.
Confirm the following setpoint parameters have been established:
Set the bake gas bypass to: OFF.
Set the U012 DIP switch to: 3 open, other closed.
Turn the Autodrain: ON
Confirm the Desorb Time; be certain the Archon and
the purge and trap times match.
