How to Access Diagnostic Buffer File from LC Modules for Advanced Troubleshooting

This Information Applies To: All Agilent LC modules.

Issue:

If there are troubleshooting issues with LC hardware as a part of an Agilent OpenLab system, Agilent Support representatives may ask you to provide them with a Diagnostic Buffer file to help solve the issue. This is a .txt file that includes additional information for all LC modules, PC hardware, and software in addition to the information shown in the System Report. Please follow this procedure to create, save, and send the file to your local Agilent Support representative.

Steps to follow:

If Agilent Lab Advisor software is not installed, or if your current system is not added in Lab Advisor, then please see the following articles for details on how to Install Lab Advisor and How to add your system.
