Agilent HPLC Quaternary Pump Leak Repair and Pressure Stability Restored
An Agilent HPLC quaternary pump leak at high pressure was reported, with visible solvent leakage during operation and instability when running standard methods. The system could not maintain proper pressure, raising concerns about pump performance and reliability. Diagnostics identified two leak points: one at the inlet tubing connection to the inlet valve, and another between the pump head and pump body. The inlet valve was removed and cleaned to eliminate salt buildup, resolving the leak at th...
