Installation
Next steps
Integrate the pump into the HPLC flow system.
Quaternary Pump
The figure shows the installation plan for capillary and tubing on
the quaternary version of the pump. If you own a different ver-
sion of the pump, see the corresponding chapter for installation
instructions.
The gray lines represent the connection of the eluents to the
pump and the black lines represent the connection of the piston
backflushing.
Piston backflushing
The flushing solution is re-used. Since the flow path is circular,
only one bottle is used for the flushing solution.
Connecting the Degasser
The degasser outlet is readily connected to the valve block.
Flow path solvent
The four solvents are connected with the inlet of the degasser.
The solvent mixture is conveyed from the degasser via the valve
block into the pump head. From the pump head it is taken to
the mixer. The mixer is connected to the HPLC system.
