4.
Insert the female end of the power cable to the power connector on the rear of the
column heater and the male end into the power source outlet.
5.
Connect the IEEE-488 signal cable to the IEEE-488 port on the rear of the column
heater. The other end of this cable must be connected to a MassLynx workstation for
software control.
6.
See
Section 2.3.2, Setting the IEEE-488 Address
, to set the column heater address.
2.4.5 Connecting the Pump Outlet
Follow the instructions in this section to connect the pump outlet to the next instrument in
the flow path. Making pump outlet connections involves:
•
Cutting the tubing
•
Attaching a compression fitting to each end of the tubing
•
Connecting each end of the tubing
Required Materials
•
Two stainless steel ferrules and standard compression screws (part number
WAT025604 in Startup Kit)
•
1/16-inch OD stainless steel tubing (in Startup Kit)
•
Circular tubing cutter (part number WAT022384) or knife-edge file
•
Needle-nose pliers (two pairs if cutting tubing with a knife-edge file)
•
5/16-inch open-end wrench (part number WAT022527 in Startup Kit)
Cutting the Tubing to Length
1.
Measure the length of stainless steel tubing required to connect the pump outlet to
the injector or other instrument.
2.
Use a knife-edge file to scribe the circumference of the tubing at the desired break.
Whenever possible, use a circular tubing cutter instead of the knife-edge file to
obtain a clean, square cut.
3.
Grasp the tubing on both sides of the scribe mark with cloth-covered pliers (to
prevent marring of the tube surface) and gently work the tube back and forth until it
snaps. Ensure that the break is square and free of burrs.
Caution:
To avoid having eluent leak from a pump outlet, position each eluent reservoir
below its corresponding pump inlet until the outlet is connected to the system.
