5. Inspect the discharge tube:
An incorrectly installed discharge tube can cause the
distributor arm to fail. It can also cross-contaminate samples.
To prevent these problems, inspect the discharge tube as
described in the following steps.
a. Manually rotate the arm to make sure that the tube
does not obstruct its movement. If the tube obstructs
arm movement, re-route the discharge tubing.
b. The discharge tube must slope downward from the
bulkhead fitting to the arm throughout the range of
arm motion. Otherwise, liquid may pool in the tube and
cross-contaminate samples.
Note that the discharge tube has a natural curve.
Should the tube create a low spot where liquid can pool,
twist the end of the tube connected to the bulkhead
fitting so that the natural curve holds the tube in a
downward sloping position. Then, retest the tube at
other arm positions.
Note
You can order replacement discharge tubes from Teledyne
