4.4 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 Dionex ICS-1100 does not contain a vacuum degas assembly, degas the
eluent manually (see Section 3.4.4
).
If the Dionex ICS-1100 contains a vacuum degas assembly, check the degas
settings:
1. Open the Chromeleon Server Configuration program. Right-click the
Dionex ICS-1100 device in the timebase and select Properties.
2. Select the Options tab (see Figure 4-1
).
