Note:
When using a Waters inline degasser, refer to the degasser operator’s guide for
details on connecting the degasser to the reservoir and pump.
Required Materials
•
Tefzel
®
ferrule and compression screw – one set per pump (in Startup Kit)
•
1/8-inch OD ETFE tubing (part number WAT270714 in Startup Kit)
•
ETFE tubing (part number WAT024036 in Startup Kit)
•
Reservoir containing filtered, degassed eluent – one per pump
•
Bottle holder
•
Bottle caps (1 L) (part number WAT062479 in Startup Kit)
•
Stainless steel solvent filter – one per pump (part number WAT025531 in Startup Kit)
•
Plastic tubing cutter (not included) (part number WAT031795) or razor blade
•
Inlet tubing labels (part numbers WAT087186[A] and WAT087187[B])
Installing the Bottle Holder
1.
Carefully position the rack along the left side of the pump so the cutouts at the
bottom inside of the rack rest on their corresponding positioning screws on the
pump.
2.
Holding the rack flush against the surface of the pump, finger-tighten the captive
screw to secure the rack.
Connecting Eluent Tubing to the Pump Inlet
1.
Measure the length of 1/8-inch ETFE tubing required to connect an eluent reservoir
(mounted in the bottle holder) to an inlet manifold on the pump. When using an inline
degasser, refer to the degasser operator’s guide for details on connecting to the
reservoir and pump.
Note:
It may be necessary to substantially increase reservoir height if you use
high-viscosity eluents (18 to 24 inches above the inlet manifold is not uncommon).
2.
Insert the ETFE tubing into the 1/8-inch diameter hole of the tubing cutter, making
sure that the tubing that extends from the metal side of the cutter is the correct
length.
3.
Insert the razor blade into the cutter and press down to cut the tubing. Make sure the
cut end is straight and free from burrs.
4.
Slide a compression screw over one end of the tubing, followed by a ferrule with its
tapered end facing away from the tubing end, and its wide end flush with the tubing
end, as shown in
.
