This manual provides symptoms associated with headspace
sampler (HS) hardware or associated chromatographic
output, Not Ready messages, and other common issues. It
also provides the corresponding tasks to perform should you
experience these symptoms.
Each section describes a problem and provides a bulleted list
of possible causes for you to troubleshoot. These lists are not
intended for use in the development of new methods. (For
help when developing methods, see the
Guide.) Proceed with troubleshooting under the assumption
that method(s) are working properly.
This manual also includes common troubleshooting tasks as
well as a list of information needed prior to calling Agilent
for service.
Use the following steps as a general approach to
troubleshooting:
Observe the symptoms of the problem.
1
Check the HS status displays and logs, especially the
2
sequence log and event log. Check the GC logs, events,
and display. If using a data system, check its logs also.
These logs may contain valuable information that directly
indicates the root cause of problem.
3 Consider what may have changed recently. See
Changed?".
Consider whether the symptom can be caused by the GC.
4
Look up the symptoms in this manual using the table of
5
contents or the search tool. Review the list of possible
causes of the symptom.
Check each possible cause or perform a test that narrows
6
the list of possible causes until the symptom is resolved.
Be sure to also use the [Status] and [Info] keys on the HS
keypad while using this troubleshooting information. These
keys will display additional useful information related to the
status of the HS and its components.
