Leak

Leak
A leak was detected in the autosampler.
The signals from the two temperature sensors (leak sensor and
board-mounted temperature-compensation sensor) are used by the leak
algorithm to determine whether a leak is present. When a leak occurs, the
leak sensor is cooled by the solvent. This changes the resistance of the leak
sensor which is sensed by the leak-sensor circuit on the ASM board.
• Loose fittings.
• Broken capillary.
• Leaking rotor seal or needle seat.
• Defective metering seal.
❏ Ensure all fittings are tight.
❏ Exchange defective capillaries.
❏ Exchange the rotor seal or seat capillary.
❏ Exchange the metering seal.
