Making fluid line connections 2-7
Requirement: You must make the following fluid line connections on your

• Column connections
• Drip management system connections
Recommendations:
• Before completing the column connections, perform the verification
procedures described in
“Verifying the detector” on page 3-27 .

tubing to connect the drain tube to the waste reservoir.
Connecting columns
The fluid line connections to the detector are located in the front right-hand
side of the flow cell assembly (see the figure below).
To make the inlet and outlet tubing connections
1. Attach the stainless steel compression fitting and ferrule (supplied in
the startup kit).
2. Connect the inlet tubing to the column outlet. Ensure the tubing is
seated firmly, then tighten the compression screw.
3. Connect the Tygon tubing to the flow cell outlet tubing and route to a
waste container.
Caution: The detector, as shipped, has a standard analytical flow cell
pressure-rated at 1000 psi. To prevent damage, do not connect any
tubing or device that might cause backpressure to exceed the
pressure rating of the tubing or flow cell.
