Maintaining Detectors in Stack Configuration
Troubleshooting Guidelines
Troubleshooting detectors in stack configuration does not differ from what you
would do if they would be installed separately. So, in case of troubles, you will
find the necessary information in the relevant chapters of this manual.
In case the ECD features an irregular response or no response at all, while the
auxiliary detector auxiliary gives a normal response, this can be due to incorrect
installation of the column inside the ECD.
To correct the symptom, reinstall the column and check it for leaks.To ensure a
right insertion of the column inside the detector base body, the distance between
the ferrule and the end of the column must be 108-110 mm.
CAUTION
When reinstalling the column, do not overtighten the connection to avoid damaging
the ferrule and the column.
