Before operating the system, fill the solvent reservoirs.

TIP

To avoid the formation of air bubbles in liquid lines, always place reservoirs in the solvent rack on top of the system stack.

Preparations

  1. Rinse the solvent reservoirs and all parts of the solvent line filter thoroughly. Use a high-purity solvent for rinsing.

  1. Assemble the solvent line filter, wearing appropriate clean gloves:

  1. Insert the solvent line adapter into the filter holder (top part).
  2. Turn the filter holder (top part) with adapter upside down and press onto a suitable surface so that the adapter is seated firmly in the filter holder.
  3. Place the frit in a level position in the filter holder (bottom part).
  4. Screw the filter top firmly to the filter bottom.

  1. Feed each solvent line through a retaining guide.

  2. Feed the solvent line through an open hole in a cap for a solvent reservoir. The retaining guide keeps the solvent line in place in the reservoir.

  3. Close any open holes in the reservoir caps with the cap plugs.

  4. Slide a solvent line filter onto each solvent line.

  1. Fill the solvent reservoirs with solvent.

  2. Tighten the reservoir cap hand-tight. Press the retaining guide into the hole in the reservoir cap so that the tubing is kept in place in the cap.

  3. Place the solvent reservoirs in the solvent rack.

  4. Position the solvent lines straight in the tubing guides.

  1. Check the solvent lines across the entire flow path. Make sure that the lines are not bent, pinched, or squeezed at any point in the flow path.
