Early maintenance feedback
Four of the most frequently replaced or serviced parts on a GC are the inlet
septum, the column, the inlet liner, and the syringe. Using Early Maintenance
Feedback (EMF) and a G2629A Control Module, you can independently track
usage of these items by number of injections. After your preset limit on the
number of injections expires, you receive a warning message on the GC front
display. This warning prompts you to replace or service the item, but readiness
is not affected. You can still continue using the GC normally.
Always service the GC when not in a run or sequence. For details on how to set
up and use EMF, see the G2629A Control Module user information.
