1 Place a needle wash solvent reservoir into the solvent cabinet.
2 Connect the Needle Wash Bottle Head Assembly to the solvent reservoir and
close the bottle.
3 Guide the tube of the Needle Wash Bottle Head Assembly through the cover
opening and connect it to the peristaltic pump.
4 Route the drainage of the washport outlet to the waste container.
5 Prime the wash tubing.
6 Install the capillary from the pump outlet into the port 1 of the injection valve.
Preparations
Module is installed in the system.
Use an appropriate solvent based on the sample and mobile phase chemistries.
The composition of the wash solvent should be the most solubilizing compatible solvent (your stron-
gest diluent). Selecting the wash solvent is part of the method development.
A mixture of 50 % up to 100 % organic solvent in distilled water is a good choice for many applica-
tions.
The silicone waste drainage is suitable for most common wash solvents. For
critical wash solvents, it may be necessary to replace the silicone tube with a PE
tube (Tubing, PE, 1.5 m (5042-9974)).
