Tip The waste tube must be positioned below the injection valve. Make sure that the
waste liquid flows into the waste container without restriction. The waste tube must
always be above the liquid level in the waste container.
Tip Before you insert a syringe, first verify the position, Change Syr. Do not locate the
Change Syringe position above an object where the needle could collide with a vial, for
example.
Path: Menu > Utilities > Syringe > function key F3 (Change Pos).
Move the PAL injection unit to a location where no collision can occur with the z axis by
selecting the x and y axes appropriately. The value for the z axis is given as a default and a
change of this position is not necessary in standard operation.
This precaution helps avoid needle damage during routine operation. Nevertheless, the
description in the next section on how to install the DLW Syringe assembly recommends
switching off the unit and inserting the assembly without using the Open Autosampler
command, Change Syringe.
The DLW Syringe Holder differs from standard liquid syringe holders. The DLW manifold is
attached to the syringe holder. The DLW Actuator/Solenoid and the Holding Loop
connecting the syringe inlet (bottom) and Syringe Needle are attached to the DLW manifold.
All of these parts are factory installed. See
