Troubleshooting and Test Functions
Leak
A leak was detected in the detector.
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 FLM board.
Probable Causes
•
Loose fittings.
•
Broken capillary.
•
Leaking flow cell.
Suggested Actions
✔
Ensure all fittings are tight.
✔
Exchange defective capillaries.
✔
Exchange flow cell.
formation
Detector leak error may be caused by the Agilent 1100 sampler. In each
sampler injection sequence, step# 2 ejects the mobile phase stored in the
metering head during the previous injection. This mobile phase is ejected
through the short plastic tube connected to port# 4 of the sampler switching
valve. The output of port# 4 is integrated into the sampler's contingency leak
drain system, which eventually terminates in the leak pan of the bottom
module of the stack - the detector. With normal injection volumes and run
times, the output of port# 4 is small, and evaporates right in the sampler leak
pan. However, the output of port# 4 is significant, and a substantial volume of
ejected mobile phase reaches the detector leak pan.
