Operating Manual
This section applies to VC‑pumps and VC‑autosamplers.
In a Vanquish Core system, normal-phase (NP) compatible solvents and
additives may be used if the pump and autosampler are modified with
the components from the Normal Phase (NP) kit.
1. Modify the pump and autosampler. See
Autosampler (} page 249).
2. Observe the specific information for operation in
with Normal-Phase Compatible Solvents and Additives
This section applies to VC‑pumps and VC‑autosamplers.
To use normal-phase (NP) compatible solvents and additives in a
Vanquish Core system
• Normal Phase (NP) kit, including NP compatible tubing and seals (for
use as both piston seals and seal wash seals)
For ordering information, see
• Tubing cutter
• Pistons (not with VC‑P21 and VC‑P33)
1. Turn off the pump flow and wait until the system pressure is down
to zero.
2. Unscrew the cap of the seal wash reservoir.
3. Together with cap, remove the seal wash line from the reservoir.
4. To empty the seal wash line, press down the lever of the seal wash
pump. Release the lever when the line is empty.
