10 Making Fluidic Connections to the 600E Pump
3. Grip the cut tubing with two pairs of smooth-jawed pliers, one on each side of the
score (Figure 2-3). Gently bend the tubing back and forth until it snaps. This leaves
the tubing bore open with a minimum of burrs.

Deburring Tubing
4. Inspect the cut for burrs or scratches and for perpendicularity. The tubing must be
completely open, without debris or burrs in the hole. If necessary, debur the hole
with a very fine file or deburring tool.
Note: The tubing end must be smooth, fully open, and without burrs to allow proper
seating in the compression fitting and to prevent particles from blocking the tubing.
5. Prior to connection, flush the tubing with solvent to remove any remaining particle.
6. Attach the individual ferrules, compression fittings, and nuts as described below and
in the column or instrument operator’s manual.
