Preparing solvent reservoirs 2-17
Preparing solvent reservoirs
Tip: When operating at high flow rates, and/or with viscous solvents, you can
remove the solvent reservoir filters if you need to reduce flow restriction.
Priming the plunger-seal-wash pump
The plunger-seal-wash solvent lubricates the binary gradient module
plungers and flushes away solvent or precipitated salts forced past the
plunger seal from the high-pressure side of the solvent piston chamber.
Required materials
• Tube adapter (see startup kit)
• 30-mL syringe (see startup kit)
• Seal-wash solution
Ensure the plunger-seal-wash supply tube is in the plunger-seal-wash solvent
container and that the plunger-seal-wash waste tube is in an appropriate
waste container.
To prime the plunger-seal-wash:
1. Connect the tube adapter to the syringe.
2. Fill the syringe with plunger-seal-wash solution, then connect the
syringe assembly to the plunger-seal-wash inlet tube.
3. In the MassLynx inlet status page, select the Additional Status tab, and
then select the Chroma button.
Warning: The binary gradient module does not require pressurized
solvent containers for reliable operation. If using pressurized
containers for blanketing large containers of solvent, do not exceed
5 psig. Pressures above 5 psi can force solvent through the internal
components of the solvent selection valve (SSV), possibly causing a
spillover into the solvent waste reservoir or an adverse mixture
with other solvents.
