When using the detector with an Agilent 7890B GC, use the
Early Maintenance Feedback (EMF) feature to track routine
maintenance. The EMF feature is available at the GC front panel
and in any Agilent data system, and can help you replace the
filters and oil before contamination becomes a problem.
The Agilent 7890B GC provides the following counters for the
SCD, NCD, and vacuum pump:
Counter type
Number of injections
Number of injections
Number of injections
Number of injections
Time (days)

If not using the GC EMF feature, manually keep a maintenance
log that tracks:
• Dates of maintenance and type of maintenance performed
• Operational changes that might impact performance, such as
changes in temperature settings and hydrogen flows
• Pressures during normal method runs
• Background signal (the difference between ozone "on" and
ozone "off")
