Setting up the plunger wash 2-35
4. Put the inlet tube back into the wash solvent reservoir.
Connecting to the injection panel (PrepLC system)
Tip: Refer to the figure “Injector panel (PrepLC system)” on page 1-13 when
following the procedure in this section.
Connecting to the purge valve and Rheodyne 3725i injector
The pump outlet connects to the injection panel with 0.020-inch ID tubing.
The PrepLC system uses the same size tubing to connect to the injector panel.
The Rheodyne injector, designed for large-scale operation, has flow passages
of 1.0-mm ID.
To connect the pump outlet to the injection panel:
1. Cut a length of tubing to extend from the pump outlet to the unused
fitting on the injector panel’s purge valve, or that goes directly to the
column inlet.
2. Install compression fittings on the pump end of the tubing as described
in “Liquid line connections” on page 2-21.
3. Tighten the fitting at the pump outlet.
4. Remove the unused nut and ferrule from the purge valve, and install
them on the other end of the pump outlet tubing. Attach the tubing to
the purge valve and tighten (see the figure “Pump outlet connection to
the column rack inlet (Delta-Prep system)” on page 2-39).
Put a waste beaker under the injector’s waste tubing (see the figure “Pump
outlet connection to the purge valve (PrepLC system)” on page 2-36).
