2-14 Installing the HPLC Pump
To connect the inlet tubing to an eluent reservoir:
1. If you have a binary pump, slide the inlet tubing label onto appropriate
tube.
2. Insert the free end of the 1/8-inch ETFE inlet tubing into the cap of an
eluent reservoir.
3. Slide one of the pieces of tubing (part number WAT024036)
approximately 2 cm over the end of the 1/8-inch ETFE tubing.
4. Insert the stainless tubing fitting on the solvent filter into the open end
of this tubing.
5. Install the cap onto the eluent reservoir, and push the tubing through
the cap until the filter reaches the bottom of the reservoir.
6. If you have a binary pump, repeat step 1 through step 5 for the second
pump assembly.
Tip:
If you are connecting the pump to a Waters 717plus or 2707 autosampler,
you can use one position of the bottle holder to hold a bottle that contains the
needle wash solvent.
Connecting the pump outlet
Follow the instructions in this section to connect the pump outlet to the
injector (or next component in the flow path). Making pump outlet connections
involves these tasks:
• 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) (startup kit)
• 1/16-inch OD stainless steel tubing (startup kit)
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.
