Suggested actions
Ensure the lower pressure limit is set to a value
suitable for the analysis.
• Make sure that the degasser is in flow path and
works correctly. Purge the module.
• Ensure solvent inlet filters are not blocked.
• Inspect the pump head, capillaries and fittings
for signs of a leak.
• Purge the module. Run a pressure test to
determine whether the seals or other module
components are defective.
