5.1.4 Calibrating the Vacuum Degas Assembly
When to Calibrate
• After every 6 months of use
1. Open the Dionex ICS-1100 Wellness Panel in Chromeleon (see
Section 5.1.1
).
2. On the Wellness Panel under Degas Calibration, select Calibrate.
The degas pump runs for 90 seconds to allow a vacuum to be created.
After 90 seconds, the vacuum degas pressure reading is recorded.
When the vacuum degas assembly is running in monitor mode, this
calibration value is used to determine when to turn on the degas
pump.
3. Click
Log to record the new calibration value in the Audit Trail.
5.2 Isolating a Restriction in the Liquid Lines
A restriction in the liquid plumbing will cause excessive system backpressure.
1. Begin pumping eluent through the system (including the columns).
2. Follow the flow schematics in Figure 5-2
or Figure 5-3 and work backward
through the system, beginning at the suppressor
Regen Out port. One at a
time, loosen each fitting and observe the pressure. The connection at which
the pressure drops abnormally indicates the point of restriction.
NOTE The numbers on the flow schematics indicate the order
in which liquid flows through the system components.
If the restriction has caused such high pressure that the system cannot be
operated, you must work forward through the flow schematic, adding parts
one at a time until an abnormal pressure increase (and hence, the restriction) is
found.
3. If the restriction is in the tubing or fitting, remove the restriction by back
flushing or by replacing the tubing or fitting (see Section 5.3
).
