Make sure the plumbing downstream from the cell is clear; a blockage may
overpressurize the cell, causing it to leak. If the problem continues, contact
Dionex for assistance.
4.3 Pump Difficult to Prime or Loses Prime
Excessive pressure fluctuations (more than 3% difference from one pressure
reading to the next) indicate that the pump is out of prime.
• Empty eluent reservoir and/or no eluent connected
Fill the reservoir. Make sure all connections are secure.
• Eluent improperly or insufficiently degassed
If the ICS-1000 does not contain a vacuum degas assembly, degas the eluent
manually (see Section 3.4.2
).
If the ICS-1000 contains a vacuum degas assembly, check the degas settings:
1. Open the Chromeleon Server Configuration program, select the ICS-
1000 device icon under the timebase and select Properties from the
Edit menu (or double-click the ICS-1000 device icon).
2. Select the Options tab (see Figure 4-1
).
