Replacing the Sampling Tip and Tubing
A scratched or otherwise damaged sampling tip may result in poor transfer of
liquid from the sample vial to the injection valve. Damage to the tubing between
the tip and the injection valve may result in liquid leaks. If you replace the
sampling tip, you must also replace the tubing between the tip and the injection
valve or optional high-pressure valve.
The Dionex AS-DV Sampling Tip Kit (P/N 071575) contains all required parts.
The following tools are needed to complete this procedure: #1 Phillips
screwdriver and 3-mm Allen wrench.
1. Disconnect the sample out line from the injection valve or optional high-
pressure valve. Remove the fitting.
2. Press the
Carousel Release
button to retract the sampling tip to its fully up
position.
3. Turn off the Dionex AS-DV power and disconnect the power cord. Raise the
top cover.
4. Remove the Dionex AS-DV front cover by gripping the indentations at each
side and pulling the cover straight off toward you.
5. Use a #1 Phillips screwdriver to remove the three flathead screws from the
sampling head tower cover (see
). Lift up the cover to remove it.
