Preparing the Autosampler
Working with waste tubing
To dispose of general waste liquids
1.
Connect the tee end of each drain tubing to the right- and left-hand
drain hose connectors.
Tip:
Point the center tee port upward.
2.
Place the other ends of the drain tubings in a waste container on the
floor.
Tip:
General waste tubing removes all liquid dispensed to the wash
position, as well as uninjected sample liquid and condensate from the
cooler.
Tip:
To keep the flow path clear, ensure that the drain or waste tubes
are untwisted.
Accommodating the wash solvent and syringe rinse
To fill the wash solvent tubing
1.
Fill a clean wash solvent bottle with wash solvent, and degas it.
Recommendation:
Use only water or organic wash solvents, preferably
distilled water and methanol (80%/20%) or mobile phase.
Recommendation:
To improve the wash solvent degassing, use a Waters
inline degasser.
Caution:
To avoid hindering waste drainage, route the waste tubing
downward, toward the waste container, with no rise in elevation.
Caution:
To avoid blockages, which can severely damage the
instrument, do not use crystalline or buffer solutions as wash solvents.
