If a problem is encountered, Agilent Technologies advises you to first follow the troubleshooting section to resolve the problem. If there is an error or fault and you follow the recommended course of action but the result is not satisfactory, then direct the matter to Agilent Technologies or your local distributor.
Malfunctions within the ELS Detector can arise from three general sources:
The ELS Detector itself can be dirty or operating outside specification.
The HPLC system has a broken, dirty, or nonoptimally operating component, but the problem is manifesting itself in the ELS Detector.
A mobile phase and/or column problem, which by its very nature is spread throughout the HPLC system but appears as a malfunction of the ELS Detector.
To troubleshoot the ELS Detector, you must be able to separate the performance of the ELS Detector within the HPLC system from its performance outside the HPLC system. This section begins with guidelines for testing the ELS Detector as a standalone.
See Module Specific Error Messages for possible causes and suggested solutions.
