Pressure of Binary Pump Above Upper Limit

Error ID: 22014

The pressure has exceeded the upper pressure limit.

Subpages

Probable cause	Suggested actions
1	Blockage in flow path after the pressure sensor.	Check for blockages in the LC system, e.g. purge valve, Jet Weaver, degraded column, column frits, needle, needle seat, capillaries etc. Check for particles in the solvent.
2	Inappropriate settings (pressure limit, flow rate).	Decrease flow rate. Increase pressure limit.
